I'm afraid finding a workaround for compilers dying on
compiler-generated code isn't going to be much fun...

Anyway, I just replaced a
        ifneq "$(INSTALL_LIBS)" ""
by
        ifneq "$(strip $(INSTALL_LIBS))" ""
(see my glasgow-haskell-bugs message of today, this usage is
recommended in make's "info" for strip.)

Now I could install ghc, remove the build-tree and get enough
free space to start compiling again.
This time I'll log everything and come back when I'm sure what
exactly is going on. (As I "remember" that 1) --with-gcc doesn't
do what it should and 2) the gcc-2.95-crash on linux seems to be
repeatable.)
