CONFIG_SHELL previously fell back to 'sh' when bash is not installed,
so I just kept it as it was.

If we had used the exact absolute path /bin/sh,
it would have worked irrespective of the PATH environment.

But, there is a counter option like this:

kbuild: /bin/pwd -> pwd

Most places use pwd and rely on $PATH lookup. Moving the remaining
absolute path /bin/pwd users over for consistency.

Also, a reason for doing /bin/pwd -> pwd instead of the other way around
is because I believe build systems should make little assumptions on
host filesystem layout. Case in point, we do this kind of patching
already in NixOS.

Ref. commit 028568d84da3cfca49f5f846eeeef01441d70451
("kbuild: revert $(realpath ...) to $(shell cd ... && /bin/pwd)").

I cannot find a way to satisfy everybody.
