Hm, so it seems we should make the test separately verify that perl -M{Opcode,
ExtUtils::Embed, ExtUtils::ParseXS} doesn't fail, so that we can fail perl
detection with a useful message?

With the meson prototype I set most optional features to "auto", except for
LLVM, as that increases compile times noticeably.
For configure we didn't/don't want to do much auto-detection, because that
makes life harder for distributors. But meson has one switch controlling all
features set to 'auto' and not explicitly enabled/disabled:
--auto-features {enabled,disabled,auto}
Override value of all 'auto' features (default: auto).
so the argument doesn't apply to the same degree there. We could default
auto-features to something else too.
There were two other reasons:
1) I got tired of needing to disable zlib, readline to be able to build on
windows.
2) Exercising all the dependency detection / checking seems important at this
stage
