[Buildroot] ccache and uclibc build

[Tal Zilcer]

Hi,

Im using buildroot for a long time now,
and I noticed that when building uclibc (as a part of building the toolchain), buildroot doesn't use ccache for the "target compiler" objects for uclibc.
Is there a specific reason why it should not use ccache for build?
Is it because the compiler didn't finish building itself? (although the gcc binary does exists)
I added a patch to use ccache("CROSS_COMPILE="$(CCACHE) $(TARGET_CROSS)" ) and it worked fine and much faster.
Does anybody knows why don't use ccache for this part of the build?

Thanks,
tal
