Fix static archives stripping (#5905)

* Do not strip static archives

Stripping static archives without more fine-grained options (e.g. `-g`)
leads to failures such as

    ld: libfoo.a: error adding symbols: archive has no index; run ranlib to add one

because GNU strip removes *every* symbol in a static archive by default.
Given that static archives are not final build artifacts (unlike
executables and shared libraries), stripping them gains little and only
causes more edge case failures.

* Gentoo's portage only strips debug information:
  https://github.com/gentoo/portage/blob/86f211e3a552753eb945670a39c1a3b14c3c3bd1/bin/estrip#L322
* Fedora also only strips debug information:
  https://github.com/rpm-software-management/rpm/blob/e9c13c6565cf4782d1f73255ee9144dd9bd2aca7/scripts/brp-strip-static-archive#L18
* Debian also only does some very light stripping:
  https://github.com/Debian/debhelper/blob/72ed1d3261730d56da6afde0ec7f52f32976e04d/dh_strip#L374

Fixes #4138

* Add test case for static archive stripping
