Subject: [PATCH] configure.ac: put back --disable-stack-protector

Put back --disable-stack-protector which has been removed by commit
70c85915eace83142b84e4f65f5db421cf0c09e3. This will allow the user to
disable it or to let a higher buildsystem such as buildroot to finely
configure it.

Indeed, without this patch, build can fail as some compilers (such as
uclibc) could missed the needed library (-lssp or -lssp_nonshared) at
linking step:

  CCLD     libsox.la
/home/fabrice/br-test-pkg/br-arm-full/host/opt/ext-toolchain/bin/../lib/gcc/arm-buildroot-linux-uclibcgnueabi/5.5.0/../../../../arm-buildroot-linux-uclibcgnueabi/bin/ld: cannot find -lssp_nonshared
/home/fabrice/br-test-pkg/br-arm-full/host/opt/ext-toolchain/bin/../lib/gcc/arm-buildroot-linux-uclibcgnueabi/5.5.0/../../../../arm-buildroot-linux-uclibcgnueabi/bin/ld: cannot find -lssp
