Bug 515155 - Avoid memcpy@GLIBC_2.14 for old Linux compatibility GCC by default optimizes memmove() calls to use __builtin_memmove(), which in turn uses memcpy() from the system GLIBC if source and target regions are known to not overlap. When compiling on a modern Linux host, this leads to pulling memcpy@GLIBC_2.14, which is not available on older Linux hosts. In order to be compatible with RHEL6/Centos6 level systems, we avoid the memcpy@GLIBC_2.14 symbol by -fno-builtin-memmove when compiling. This is only done for gtk2; we do not care about gtk3, since systems that have gtk3 are supposed to also have memcpy@GLIBC_2.14.
