R devel - Jul 2021 - tools::update_pkg_po() doesn't work on Solaris?

Hi all,

I am about 99% sure tools::update_pkg_po() is using an invocation that
is not supported by the Solaris version of msgfmt.

The invocation[1]:

msgfmt -c --statistics -o /path/to/file.mo /path/to/file.po

AFAICT neither -c nor --statistics appear to be supported by Solaris [2]:

I don't have access to a Solaris machine where I can try this, but I
did manage to get r-hub to pass by disabling those options in potools
which similarly relies on msgfmt to generate .mo files [3], [4].

So I wanted to check with the list if anyone can confirm this before
filing a bug report.

Thanks,
Mike C
