cc/gcc: diable libsanitizer without NPTL

gcc-4.8 comes with a new library to sanitise memory access:
- heap-, stack-, and global-buffer overflow, use-after-free
- data-races between threads

This library requires some _np parts of the API, which are not
implemented in the (old) LinuxThreads, which is still available
in uClibc.

Since NPTL requires a i486 or above, i386 are stuck with using LT,
which precludes building the libsanitizer.

Disable libsanitizer, a bit like libatomic is.

     1 do not bother running ldconfig on DESTDIR.  it wants to write the temp cache

     2 file outside of the chroot.  doesnt matter anyways as we wont use the cache

     3 results (portage will rebuild cache), so running ldconfig is simply a waste

     4 of time.
