There is a nice construct in bash (beware: version 4 only) which
allows you to make something uppercase with brace expansion.
Look at this:

[bardo at antani ~]$ pkgver=2.0.1-beta1
[bardo at antani ~]$ echo ${pkgver^^}
2.0.1-BETA1

The only problem in your specific situation is the need to also change
'-' in '_'. That would require a double brace expansion, but I'm not
sure it is possible. If it is, it seems to be undocumented. The
cleanest way I could come up with is:

$(sed 's/-/_/' <<<${pkgver^^})

Not very nice, huh? :)
