>Description:
I have -current sources extracted from tarballs downloaded today. I am building evbmips userland with CPUFLAGS=-mips32r2:

$ ./build.sh -U -u -m evbmips -a mipsel -V CPUFLAGS="-march=mips32r2" release


Build fails in src/sys/arch/evbmips/stand/sbmips:

cc1: error: '-mips64' conflicts with the other architecture options, which specify a mips32r2 processor


The conflicting flags come from src/sys/arch/evbmips/stand/sbmips/Makefile.bootprogs.  I am not trying to build for a Broadcom board so I think these programs are unnecessary.
>How-To-Repeat:
$ cd /usr/src
$ ./build.sh -U -u -m evbmips -a mipsel -V CPUFLAGS="-march=mips32r2" release

>Fix:
Removing the -mips64 flags from stand/sbmips/Makefile.bootprogs worked for me.  I don't know if these sbmips bootprogs still work like this since I am not using that particular platform.
