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.
