Yes. You are correct.
I guess `%(cc1_cpu)` was supposed to contains all of switches support
by the author of this specs file,
while this suppose is not true.

Such as mips, the EL/EB option is added by
#undef CC1_SPEC
#define CC1_SPEC "\
%{G*} %{EB:-meb} %{EL:-mel} %{EB:%{EL:%emay not use both -EB and -EL}} \
%(subtarget_cc1_spec)"

And it is also true for most target, since they are using
`%(subtarget_cc1_spec)` or similar.
