Add Gnulib portability modules; update Gnulib files.
* m4/gnulib-cache.m4 (gl_MODULES): Add `flock' (provides flock(2)
declaration and implementation), `fpieee' (fixes floating point
behavior on Alpha and SH), `stdlib' (provides an unsetenv(3)
declaration, among others), `putenv' (provides a putenv(3) declaration
and implementation with the semantics we need).
