Thanks!
I've changed the port devel/powerpc64-gcc (master port for devel/mips-gcc) slightly
to build gcc-6.2.0 instead of gcc-5.3.0 and it builds and installs just fine
using command make FREEBSD_EXTENSION=yes install
Then, I've installed devel/mips-xtoolchain-gcc and run buildworld using CROSS_TOOLCHAIN=mips-gcc.
It fails:

I try to build code for TP-Link WDR3600.
I'm not familiar with MIPS assembler. Is there a way to alter gcc6 code generator to avoid this error?
