So I was looking at removing it, but it turns out t-mips-img tries to 
build a multilib using -fshort-double. Matthew - is this really 
required? I tried to build a mips-img-elf compiler, but building libgcc 
fails with

conftest.c:1:0: error: unsupported combination: 'mips32r6' 
-mno-explicit-relocs
 /* confdefs.h */


conftest.c:1:0: error: '-mno-gpopt' needs '-mexplicit-relocs'
