[hppa-linux] Preliminary patch for egcs-1.1.1

[hppa-linux] Preliminary patch for egcs-1.1.1

[Paul J.Y. Lahaie]

[-- Attachment #1: Type: text/plain, Size: 221 bytes --]

Here is a first patch for egcs-1.1.1 to support hppa1.1-hp-linux. 
I've gotten it to cross-compile into the libgcc2.a but the GNU assembler
fails because it doesn't recognize the ";" character as a comment.
