PATCH: PR libjava/3207: Ignore _AC_ARG_VAR_PRECIOUS

[H. J. Lu]

Both libstdc++ and libjava have the same kludge to ignore
_AC_ARG_VAR_PRECIOUS to make sure that CC, CFLAGS, CXX, CXXFLAGS
and LDFLAG won't be 'precious' to support multilibs. However,
the new libtool makes the kludge ineffective. As the result,
CXX and CXXFLAGS in libjava are 'precious' and libjava won't build
since the new libtool was introduced:

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32078

This kludge totally ignores _AC_ARG_VAR_PRECIOUS and allows me to
build libjava. For some reason, libstdc++ is OK. I assume that
the old kludge in libstdc++  is no longer needed for the new libtool.
