Subject: mips gcc wrapper issue
I have an odd issue with the gcc wrapper on my mipsel box
building git head with nothing set except CFLAGS='-march=mips3 -mplt
-Wa,-mfix-loongson2f-nop' when I run the wrapper it has added a flag
-EL which gcc doesnt understand, so it cant compile anything. Looking
at the wrapper I cant see anything odd, really cant work out whats
wrong...

Using built-in specs.
Reading specs from /usr/local/musl/lib/musl-gcc.specs
rename spec cpp_options to old_cpp_options
