[parisc-linux] libgcc

[willy]

I've committed some changes which should allow gcc to build libgcc.a.
Compilation stops when trying to test libgcc:

Testing libgcc1.  Ignore linker warning messages.

I don't see $global$ defined anywhere.  Is this something which ld should
be fixing-up and isn't?

Yes, the HP loader defines this symbol.  It is used to access global
symbols.  If you are using ELF (GNU ld), this may not be defined.  I few
months ago I hacked the milli library to add this to libgcc.a.  However,
it really should be defined by the linker.
