[PATCH v2] gcc: Fix setting of GLIBC_DYNAMIC_LINKER

[Kumar Gala <galak@kernel.crashing.org>]

The sed regex in do_configure_prepend was producing the following result:

 #define GLIBC_DYNAMIC_LINKER64 SYSTEMLIBS_DIR "/lib64/ld-linux-x86-64.so.2"

instead of removing the leading "/lib" or "/lib64".

Now we have it do:

 #define GLIBC_DYNAMIC_LINKER64 SYSTEMLIBS_DIR "ld-linux-x86-64.so.2"

Additionally, with the regex fixed the manipulation of SYSTEMLIBS_DIR
needs to be removed.

Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* cleanup regex so we dont add in / explicity but just pull it in from 
  how SYSTEMLIBS_DIR is set.
