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.

    12       Crosstool-NG relies on some external tools to be recent enough, namely:
    13         make = 3.81 (in some cases)
    14         m4 >= 1.4.12
    15         autoconf >= 2.63
    16         automake >= 1.10.2
    17         libtool >= 2.2.4
    18       
    19       If your system has older versions, we can build them for you,
    20       but you are strongly encouraged to update your system instead!
