New Revision: 216113
URL: http://svn.freebsd.org/changeset/base/216113
Log:
The driver-XXX.c files used for host CPU detection with -march=native
should not be compiled in the cross-tools case (where -march=native makes
no sense). This fixes cross-building x86 toolchains on non-x86 systems.
I think it's wrong. And it seems people running into the case now
cross compiling i386 on amd64 not picking up driver-i386.c anymore and
thus missing host_detect_local_cpu.
It could be this is related to a fix I had started to do for the
cross-gcc port:
http://people.freebsd.org/~bz/20101202-01-ports-devel-cross-gcc-za.diff
(the port still dies later on, thus not submitted yet).
but given that it was fine before, yu are simply removing the extra
file from compilation in that case now as I understand.
