[Bug libstdc++/15390] New: No DESTDIR for libstdc++ includes

["lloyd at must-have-coffee dot gen dot nz" <gcc-bugzilla at gcc dot gnu dot org>]

Files from libstdc++-v3/include/bits cannot be installed when DESTDIR is set.
The definition of DESTDIR is being ignored. This appears to be because even
though libstdc++-v3/include/Makefile.am doesn't recurse through subdirs, make
does call itself recursively and the definitions of AM_MAKEFLAGS and
FLAGS_TO_PASS aren't set up for this. The error messages are rather long, so
I'll add them as an attachment. I'm in the process of creating and testing a
patch but that may take several days.
