Add the Linaro GNU 5.1 Binary Toolchain
Add the Linaro GNU Binary Toolchain as a third party prebuilt.
This is needed for the aarch64 cross compiler (gcc), to
facilitate CI testing.

+<a name="index-Symbols-in-position_002dindependent-code_002c-CRIS"></a>
+<a name="index-CRIS-symbols-in-position_002dindependent-code"></a>
+<a name="index-Position_002dindependent-code_002c-symbols-in_002c-CRIS"></a>
+
+<p>When generating <a name="crispic"></a>position-independent code (SVR4
+PIC) for use in cris-axis-linux-gnu or crisv32-axis-linux-gnu
+shared libraries, symbol
+suffixes are used to specify what kind of run-time symbol lookup
+will be used, expressed in the object as different
+<em>relocation types</em>. Usually, all absolute symbol values
+must be located in a table, the <em>global offset table</em>,
+leaving the code position-independent; independent of values of
+global symbols and independent of the address of the code. The
+suffix modifies the value of the symbol, into for example an
+index into the global offset table where the real symbol value
+is entered, or a PC-relative value, or a value relative to the
+start of the global offset table. All symbol suffixes start
+with the character ‘<samp>:</samp>’ (omitted in the list below). Every
+symbol use in code or a read-only section must therefore have a
+PIC suffix to enable a useful shared library to be created.
+Usually, these constructs must not be used with an additive
+constant offset as is usually allowed, i.e. no 4 as in
+<code>symbol + 4</code> is allowed. This restriction is checked at
+link-time, not at assembly-time.
+</p>
+<dl compact="compact">
+<dt><code>GOT</code></dt>
+<dd>
+<p>Attaching this suffix to a symbol in an instruction causes the
+symbol to be entered into the global offset table. The value is
+a 32-bit index for that symbol into the global offset table.
+The name of the corresponding relocation is
+‘<samp>R_CRIS_32_GOT</samp>’. Example: <code>move.d
+[$r0+extsym:GOT],$r9</code>
+</p>
+</dd>
+<dt><code>GOT16</code></dt>
+<dd>
+<p>Same as for ‘<samp>GOT</samp>’, but the value is a 16-bit index into the
+global offset table. The corresponding relocation is
+‘<samp>R_CRIS_16_GOT</samp>’. Example: <code>move.d
+[$r0+asymbol:GOT16],$r10</code>
+</p>
+</dd>
+<dt><code>PLT</code></dt>
+<dd>
+<p>This suffix is used for function symbols. It causes a
+<em>procedure linkage table</em>, an array of code stubs, to be
+created at the time the shared object is created or linked
+against, together with a global offset table entry. The value
+is a pc-relative offset to the corresponding stub code in the
+procedure linkage table. This arrangement causes the run-time
+symbol resolver to be called to look up and set the value of the
+symbol the first time the function is called (at latest;
+depending environment variables). It is only safe to leave the
+symbol unresolved this way if all references are function calls.
+The name of the relocation is ‘<samp>R_CRIS_32_PLT_PCREL</samp>’.
+Example: <code>add.d fnname:PLT,$pc</code>
+</p>
+</dd>
+<dt><code>PLTG</code></dt>
+<dd>
+<p>Like PLT, but the value is relative to the beginning of the
+global offset table. The relocation is
+‘<samp>R_CRIS_32_PLT_GOTREL</samp>’. Example: <code>move.d
+fnname:PLTG,$r3</code>
+</p>
+</dd>
+<dt><code>GOTPLT</code></dt>
+<dd>
+<p>Similar to ‘<samp>PLT</samp>’, but the value of the symbol is a 32-bit
+index into the global offset table. This is somewhat of a mix
+between the effect of the ‘<samp>GOT</samp>’ and the ‘<samp>PLT</samp>’ suffix;
+the difference to ‘<samp>GOT</samp>’ is that there will be a procedure
+linkage table entry created, and that the symbol is assumed to
+be a function entry and will be resolved by the run-time
+resolver as with ‘<samp>PLT</samp>’. The relocation is
+‘<samp>R_CRIS_32_GOTPLT</samp>’. Example: <code>jsr
+[$r0+fnname:GOTPLT]</code>
+</p>
+</dd>
+<dt><code>GOTPLT16</code></dt>
+<dd>
+<p>A variant of ‘<samp>GOTPLT</samp>’ giving a 16-bit value. Its
+relocation name is ‘<samp>R_CRIS_16_GOTPLT</samp>’. Example: <code>jsr
+[$r0+fnname:GOTPLT16]</code>
+</p>
+</dd>
+<dt><code>GOTOFF</code></dt>
+<dd>
+<p>This suffix must only be attached to a local symbol, but may be
+used in an expression adding an offset. The value is the
+address of the symbol relative to the start of the global offset
+table. The relocation name is ‘<samp>R_CRIS_32_GOTREL</samp>’.
+Example: <code>move.d [$r0+localsym:GOTOFF],r3</code>
+</p></dd>
