Package: gcc-7 Version: 7.2.0-19 msa.h should be include into libgcc-?-dev package. Since MSA is only available (and yet optional) for MIPS r5/r6, this is not enabled by default.
Anyway this header should be installed. do *NOT* apply this patch to gcc-6, as gcc-6 seems have not MSA support. -- YunQiang Su
