: mipsEEel-netbsd-gcc fixes EE miss-prediction of branch targets for

: mipsEEel-netbsd-gcc for kernel compile.
Is this just an optimization issue (slower code from mipsel compiler), or
does the standard mipsel compiler produce broken code (kernel panics)?
If only optimization, we should still use the standard mipsel compiler by
default. This would allow us to cross-build the "normal" way for 1.6, on
the bulk build machine. If users want to use custom mipsEEel compiler to
make a custom kernel, that is OK, but it should be optional.
Is there anything else that would make the standard mipsel compiler not work
for playstation2 kernel compiles?
