New review comment by Piraty on void-packages repository

Comment:
first, your list is incomplete as is (should use starred globs for `armv[67]`, as `armv7l-musl` isn't disallowed currently).

second, your point of restricting archs is to break early and not fail mid dependency installation step due to missing dependency `libomp-devel` , isn't it?
so it's technically incorrect to mix whitelist and blacklist this way, as using the blacklist like you do here makes it try build for archs that don't support libomp per llvm12's whitelist, for example `ppc`, `mips*`, `armv5*`.

so you either blacklist *all* unsupported archs (which are a lot and adds maintenance burden, so please don't) or duplicate the whitelist here to be explicit in sync with the limitation imposed by llvm12, therefore make it easy to maintain and technically correct
