v3: fix config.status instantiation of subdir makefiles.

libstdc++-v3/:
* configure.ac: Replace AC_CONFIG_COMMANDS([default])
instantiation with additional commands issued for each Makefile
in glibcxx_SUBDIRS, so `./config.status subdir/Makefile' also

Add a separate AC_CONFIG_COMMANDS([generate-headers]) for
running `make' in include, passing `pch_build=' to `make'.
* configure: Regenerate.
