With this flag, goma's client (gomacc) fails when local
compiler is different from goma's. Without this, goma's
backend finds a fallback compiler which looks closer to the
local compiler using version info, etc.

User can overwrite NINJA_REMOTE_NUM_JOBS for this purpose. The
number is passed to ninja instead of to kati so no we don't
need to regenerate a ninja file when a user changes this value.

Now ninja build is disabled only with USE_NINJA=false. So goma.mk
should fail with an error only when USE_NINJA=false is explicitly
specified.

With USE_GOMA, the path to gomacc in $GOMA_DIR or $HOME/goma
will be appended to CC_WRAPPER and CXX_WRAPPER.
Note this works only with USE_NINJA. Unlike ninja, GNU make
cannot change the parallelism depending on targets. Specifying
-j500 to GNU make would mean you may run 500 local jobs in
parallel, but with -j32 goma will just slow down the build.
