[arch-dev-public] Install files in [core]

[Allan McRae]

Hi,

With adding install files to deal with info pages to packages in [core], 
there are a number of packages with install files that will cause errors 
if bash is not installed before them (pacman uses /bin/sh from the 
system it is installing to).

An incomplete list:
binutils
diffutils
ed
filesystem  (also needs coreutils for chmod)
findutils
gcc-libs  (fixed in git)
gdbm
gettext
gmp
gpm

How do we handle this?  Add "sh" to dependencies?  Not have post_install 
for these packages (it is only info page installs...)?  I did the later 
for gcc-libs where it makes sense but other cases are not so clear cut.
