There was a typo here, a missing word between "process" and "using".

Those lines were slightly too long.

You should have replicated the BR2_USE_MMU dependency here.

bash is not needed at build time, it's only a runtime dependency, so
I've removed it from this variable (but kept it as a select in
Config.in, and added a comment that indicates it's a runtime
dependency).
It's worth noting that with uClibc, a number of tests fail to build,
but I guess that's expected, and it doesn't abort the build.
I've applied with the fixes I mentioned above.
Thanks!
Thomas
