Not all versions of sed have the --in-place flag. Detect support for the flag during ./configure and provide a fallback mechanism for those systems where sed's behavior differs. The autoconf variable ${ac_inplace} can be used to choose the correct flags for editing a file in place with sed. Replace violating usages in Makefile.am with ${ac_inplace}.
