Subject: Fix build failure on power4 processors
X-Git-Tag: glibc-2.18~888
X-Git-Url: https://sourceware.org/git/?a=commitdiff_plain;h=b18decba11693f53a91c527cbbcef73aac7dd3e6;p=glibc.git

Fix build failure on power4 processors

The power4-specific mpa.c depended on some global variables that were
removed by earlier patches.  Also, it did not define mpone and mptwo.
