Subject: [PATCH] remove selftests

When the gcc archive is extracted by the gcc.mk, the gcc/testsuite
is excluded:

HOST_GCC_EXCLUDES = \
	libjava/* libgo/* \
	gcc/testsuite/* libstdc++-v3/testsuite/*

The new Makefile target from the "Selftest framework" [1] added a dependency
on the gcc/testsuite/Makefile.
Revert partially the commit [1] to allow building gcc without selftest.
