libjpeg-turbo fails to build from source on mips* with the following
error:

| ^~~
| jsimd_mips.c:82:3: note: each undeclared identifier is reported only once for
each function it appears in
| Makefile:596: recipe for target 'jsimd_mips.lo' failed
The problem is that the env variable is not declared in the MIPS
specific code. The following simple patch fixes the issue:
