libc/glibc: add fortify option

By default, recent versions of glibc and eglibc will build some
functions that take format strings (eg. printf, syslog...) with
run-time checks against some format string attacks. This is
called a fortified build.

Unfortunately, this fails somehow while building the instrumented
version of syslog, with some kind of circular dependency...

Disable fortified builds by default, and hide the enabling option
behind EXPERIMENTAL for daring users...

     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.

     8 

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

    10 in regex_internal.h
