environment: Assume that mips64 can run 32-bit mips binaries

The relationship between mips64 and mips is similar to the relationship
between x86_64 and x86. Representing it here is necessary so that we
will not require an exe_wrapper when cross-compiling for 32-bit mips on
mips64, or when a complete 32-bit mips user-space runs on a 64-bit kernel
without using linux32 to alter uname(2) to pretend to be 32-bit.
