gcc: create symbolic link to ld-linux in EABIhf/gcc 4.7/eglibc 



When using eglibc, the ld-linux loader is installed as
ld-linux-armhf.so.3, but gcc 4.7.x was not yet updated, and generates
binaries that reference ld-linux.so.3. This was fixed starting with
gcc 4.8.x. In order to be able to use gcc 4.7, we create the
appropriate symbolic link.

# In gcc 4.7.x, the ARM EABIhf library loader path for eglibc was not

# correct, so we create a symbolic link to make things work

# properly. eglibc installs the library loader as ld-linux-armhf.so.3,

# but gcc creates binaries that reference ld-linux.so.3.
