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...

     9 Hi Robert,
    10 
    11 I've attached two patches:
    12 
    13 1/  For crosstool-0.31 which changes the CYGWIN_URL to one which has the
    14 cygwin source archives.  The version of cygwin that is used to build the
    15 cross toolchain has been changed to cygwin-1.5.15-1-src.tar.bz2 since
    16 most of the mirror sites don't seem to have the original archive used.
    17 [created gcc-3.3.2-cygwin-1.5.15-1.dat - dank]
    18 
    19 
    20 2/ The later cygwin source archive fails to cross build with the error:
    21 /opt/crosstool/i686-pc-cygwin/gcc-3.3.2-cygwin-1.5.15-1/lib/gcc-lib/i686-pc-cygwin/bin/ld:
    22 cannot find -luser32
    23 
    24 unless the second patch is applied,
    25
