Subject: Configure: add mechanism to specify uplink target architecture
X-Git-Tag: openssl-3.0.0-alpha1~1930
X-Git-Url: http://git.ipfire.org/?p=thirdparty%2Fopenssl.git;a=commitdiff_plain;h=b19fe714e9d4c50dcb33259346f06d3924b337b7

Configure: add mechanism to specify uplink target architecture

As preparation for moving uplink file specs to build.info files, we
must make sure there is still some base information to help select the
correct files.
