Hi!
In my redhat/gcc-4_7-branch build with -fexceptions in XCFLAGS
(comes from standard Fedora optimization flags) I got many libitm
testsuite failures, because libitm currently relies on -fno-exceptions
as it is not linked against -lstdc++.
Fixed by putting XCFLAGS first and thus overriding those with
-fno-exceptions -fno-rtti. E.g. gcc/Makefile.in also overrides
user given flags with -fno-rtti -fno-exceptions.
Bootstrapped/regtested on x86_64-linux and i686-linux, ok for trunk?

* Makefile.am (AM_CXXFLAGS): Put $(XCFLAGS) first.
* Makefile.in: Regenerated.
