Revision 1.98, Sat Sep 23 12:35:52 2017 UTC (6 years, 7 months ago) by patrick
Branch: MAIN
CVS Tags: OPENBSD_6_2_BASE, OPENBSD_6_2
Changes since 1.97: +8 -5 lines

Compile the cross-compiler in the target's objdir instead of polluting
the host's.  This also allows compiling multiple toolchains in parallel.
Clean up the clang object files afterwards so it doesn't collide with
the cross-compiled compiler build.
