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.

     3 A compilation of an ARM toolchain with glibc 2.7 using crosstool-ng

     4 failed with a gcc error in glibc-2.7/posix/regex_internal.c, more

     5 concretly in the function build_wcs_upper_buffer(). The return type of

     6 the function prototype in regex_internal.h doesn't correspond with the

     7 return type of this function in regex_internal.c.

     9 The attached patch corrects the return type of the function prototype

    10 in regex_internal.h
