Patchwork [2/4] eglibc: Only add eglibc-utils to PACKAGES if wchar is supported

eglibc-utils RDEPENDS on bash which requires gettext which requires
wchar support. If wchar support is not included in DISTRO_FEATURES,
gettext will fail to compile.

By removing eglibc-utils from the PACKAGES listing, bitbake doesn't
try to build the dependency chain.

What code in there actually depends on bash and can't we fix it to work with stock sh?

I believe it is xtrace and tzconfig (or tzselect?) that depend on
bash. I'm sure this is fixable. If we were to fix it, I would also
want to separate out eglibc-utils as a separate recipe or somehow make
it optional to install. I believe there will continue to be
refinements to how we package eglibc in support of tiny distros.

xtrace looks easy enough to fix, although it also assumes wants a
terminal program and defaults to xterm. So we should also depend on
screen or similar.

Not sure about tzconfig/select. Will have a closer look next week.

Can we use this as is for now and improve it over time as we look at
other eglibc packaging issues?
