Bug#802550: x264: FTBFS on mipsel: Error: opcode not supported on this processor: mips2 (mips2) `addvi.b $w0, $w1, 1'

[Sebastian Ramacher]

Package: x264
Version: 2:0.148.2601+gita0cd7d3-1
Severity: serious
Justification: fails to build from source (but built successfully in the past)

x264 failed to build on mipsel:
| # Build static lib
| LDFLAGS="-Wl,-z,relro" ./configure --prefix=/usr --libdir=/usr/lib/mipsel-linux-gnu --extra-cflags=-fno-aggressive-loop-optimizations --enable-static --disable-cli \
|    || ( tail -v -n +0 config.log config.log ; exit 1 )
| You specified a pre-MSA CPU in your CFLAGS.
| If you really want to run on such a CPU, configure with --disable-asm.
| ==> config.log <==
