| Subject: [PATCH] build: undefine "mips" to prevent build problems for MIPS |
| targets |
| |
| It turns out that the MIPS GCC compiler defines a "mips" cpp macro |
| which was resulting in build failures on MIPS so we need to |
| undefine the "mips" macro during build. As this should be safe |
| to do in all architectures, just add it to the compiler flags by |
| default. |
| |
| This was reported in the following GH issue: |
