[oe] [PATCH] [RFC][PATCH] autotools: don't specify --target when configuring gmp

[Ben Gardiner]

When trying to build angstrom-2008.1 from
f58a5d59b755bdb725497f574a8059529c134c27 of master or from
b78fc95424b5f0fb28246e8c61bb8b4d6a9d733a of stable/2009 the builds failed on
gmp-native (then later gmp). The error was that "--target is not appropriate
for GMP".

This patch adds an exception to the packages for which --target will be passed
to configure. The do_configure stage of the autotools class is modified to not
pass --target if the package is "gmp" or "gmp-native".

A similar change was needed also for the stable/2009 branch -- but this patch
is not applicable to that branch as-is.

Checking the PN for a blacklist of names seems very ugly -- I am open to
suggestions on how this might be better accomplished. Also, I think that the
supressing --target may be applicable to anything that is not a cross-development
tool in general [1]; this is the minimum to get a build without errors so far.
