Thomas Petazzoni 73aed53c82 package/bash: use --bindir instead of exec_prefix=
We want bash to be installed as /bin/bash. For ages, Buildroot has
been doing this by overriding exec_prefix at install time. First of
all, it would be preferred to do this at configure time. But also,
overriding exec_prefix not only changes where "bash" goes, but also
where the pkgconfig file goes. Due to this, bash.pc goes into
/lib/pkgconfig/, and doesn't get removed by target-finalize.

Since all we want is to have 'bash' as /bin/bash, simply pass
--bindir=/bin at configure time. This allows to use the default target
installation logic for autotools-package. We keep a post-install
target hook to remove /bin/bashbug.
