cc/gcc: Fix dynamic linker path for hard float libc
When compiling glibc 2.16 and gcc 4.7.4 with CT_ARCH_FLOAT="hard",
I end up in a dynamic linker called /lib/ld-linux-armhf.so.3, but
gcc compiles the binaries with an ELF interpreter /lib/ld-linux.so.3.
That doesn't work.
This patch (which is included in recent gcc version and also is included
in Linaro 4.7 versions) fixes the problem. I just stripped the ChangeLog
diff from the original commit.
