LIB_PATH=foo make will not work.  LIB_PATH gets overridden in the
recursive make call if you do it that way.  That's why I had to set
$(MAKE) instead.  This was just to avoid slapping Yet Another local
patch on binutils...

Yes, definitely.  I'm only using the environment variables because I
didn't want another patch to binutils floating around and didn't have
time to solve the problem properly when I first did it.


To insert my two cents for a configure option: when cross-compiling,
you don't necessarily have complete control over where all the
libraries are.  This happens, for instance, when some of your libraries
are kept on an NFS mount separately from the toolchain, and some are
local.  I actually make use of this every day.
