2.52, current: Don't set program_prefix when target = host

[Maciej W. Rozycki]

Hello,

 Autoconf incorrectly sets "program_prefix" to "${target_alias}-" whenever
"target_alias" is specified, even if it's the same as "host_alias" (which
means binaries to be built will not be cross-tools).  Here is a fix. 

 For current the patch has to be applied to lib/autoconf/general.m4.

        * lib/autoconf/general.m4 (AC_CANONICAL_HOST):  Don't set
        program_prefix if target_alias equals host_alias.
