If you use the rpm backend, the python/perl/bash dependencies should already
be there with or without these patches since the rpm can scan the depends
of bash/perl/python and install it, these patches should not affect the
image's size.

If you use dpkg or ipkg backend, they can't work even they are installed
since lacks of interprets.

For gzip, it is because:

Subject: [PATCH 22/40] gzip: add bash to RDEPENDS_gzip

Bash scripts:
gzip/bin/zcat.gzip
gzip/bin/gunzip.gzip
gzip/bin/uncompress
gzip/usr/bin/zfgrep
gzip/usr/bin/gzexe
gzip/usr/bin/zdiff
gzip/usr/bin/zegrep
gzip/usr/bin/zforce
gzip/usr/bin/zmore
gzip/usr/bin/zcmp
gzip/usr/bin/zless
gzip/usr/bin/znew
gzip/usr/bin/zgrep

[YOCTO #1662]

I've looked at the files, there is a #!/bin/bash in the header, I've listed
the files which require python, perl and bash in each commit message.

That should be the next work if we really need remove the bashism or
package it separately, they can't work without the bash/perl/python
installed on the target image at the moment (if you use ipkg or dpkg).
I don't think that we have to remove bashsim or packaged separately for
each one.
