doc/texi2pod: make references bold

Inspired by GCC r86635.

This is more consistent with other man pages. For example in `man git`,
all the "git-help(1)" kind of cross refs are bold.

configure: Remove dcbzl check for e500v1 and e500v2 architectures

The DCBZL instruction is not available for the e500v1 and e500v2
architectures, but may still be recognized by the toolchain, so we need to
remove the test for it explicitly for these architectures.
