Finally - some success with cross

Finally - some success with cross

[Neal Becker]

I finally am having some success building egcs-1.0 for
host=hppa1.1-hp-hpux9
target=m68k-unknown-coff

The thing kept dying when building target libiberty.  The problem was
that the gcc was built using libgloss.h in the configure.  This does:

 * Don't set the target flags, this is done by the linker script */
#undef LIB_SPEC
#define LIB_SPEC ""

Well, it doesn't install any linker script.  So links weren't working, 
so the "needed" file of target libiberty was incorrect.

I editted <builddir>/gcc/specs to say:*lib:
%{!shared:%{g*:-lg} %{!p:%{!pg:-lc}}%{p:-lc_p}%{pg:-lc_p}}

Now the build is proceeding OK.

Well, egcs isn't supposed to install a linker script :-)  That's done
when you build gnu-ld :-)

But the linker script in egcs/gcc/specs was being used when we go to
build egcs/libiberty for the target.  So I had to edit the linker
script in egcs/gcc in order to build egcs/libraries.  (At least,
that's the way I remember it).
