[parisc-linux] [PATCH] hppa libgcc-compat

[Carlos O'Donell <carlos@baldric.uwo.ca>]

libc-alpha,

Seeing Lu's post about libgcc-compat reminded me that I should submit
our version.

We have been using this patch to fix the leaked __clz_tab symbol from
libgcc. Attached is the required additions to our Makefile, Dist, and
Versions.

This patch was produced by Randolph Chung, many thanks!

Cheers,
Carlos.
