Hi!
This fixes build against oldish glibcs, where posix_memalign has not been
declared with the default feature test macros, but has been present in the
library, so HAVE_POSIX_MEMALIGN is defined.
Fixed thusly, bootstrapped/regtested on x86_64-linux and i686-linux,
committed to trunk and gcc-9-branch.
