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...

older verisons of glibc would build dl-sysdep as shared-only and dl-support as
yann@1625
     2
static-only.  alpha hooks in a cache variable via dl-auxv.h.  newer versions of
yann@1625
     3
glibc build dl-sysdep as both shared and static which means we now have symbol
yann@1625
     4
duplication for static builds with dl-sysdep and dl-support.  since dl-sysdep
yann@1625
     5
is both shared/static, there is no point in hooking dl-support anymore, so we
yann@1625
     6
can punt it.
