I still think your previous concerns about the '=' notation are valid,
and I have yet to see those addressed.  Why is it necessary in the first

Furthermore, do these patches address the issue that -L$libdir and
-Wl,-rpath,$libdir are passed even when $libdir (or $sysroot$libdir) is
in $sys_lib_search_path_spec?  Besides causing erroneous -L flags
pointing to the native root, this currently leads to ELF RPATHs pointing
to the sysroot even when packages are configured with --prefix=$prefix.

You're being surprisingly optimistic given their track record.  Sigh,
alright, I'll let this go a few more days, but I'd really like to get
this release out already so that we can move on to other things.
