Properly test for madvise on Solaris 10 (PR bootstrap/50777)
PR bootstrap/50777
* configure.ac: Save and restore CXXFLAGS around
gcc_AC_CHECK_DECLS uses.
Check for madvise() declaration with g++ if --enable-build-with-cxx.
* configure: Regenerate.
* config.in: Regenerate.
* ggc-page.c (USING_MADVISE): Also check HAVE_DECL_MADVISE.
