linuxthreads.old: refactor nommu logic a little to avoid mmu warning
Should be no functional changes; just fixing: libpthread/linuxthreads.old/manager.c: In function 'pthread_free': libpthread/linuxthreads.old/manager.c:707:9: warning: variable 'h_bottom_save' set but not used [-Wunused-but-set-variable] Signed-off-by: Mike Frysinger <vapier@gentoo.org>
