3.1: Make install fails for libstdc++/multilibs/alternate prefix


[Please CC me, I don't read libstdc++@]

The libstdc++ Makefile has only $(AM_MAKEFLAGS), but multi-do
references $(FLAGS_TO_PASS).  Which is coming from somewhere in the
environment, and does not include things like $(gxx_include_dir); so it
tries to install headers for the multilibbed versions straight into
/usr/include.

I added "FLAGS_TO_PASS = $(AM_MAKEFLAGS)" and it worked fine, but I'm
not 100% sure those flags are safe to pass during build; they should
be, I think...  Is that a correct change?


FWIW, libjava has the same problem, but doesn't happen to hit it.
