Steps to reproduce the problem:
1. gn gen out-gn/mipsel-android --args="target_os=\"android\" is_debug=false target_cpu=\"mipsel\""
2. ninja -C out-gn/mipsel-android monochrome
3. 

What is the expected behavior?
Build to succeed.

What went wrong?

The issue is introduced with:

where hashstyle gnu is forced for monochrome target.

MIPS architecture does not support hashstyle gnu.
