fix: --without-sysreqs works

Fix #184

[eitsupi]

I'm not sure if this solution is correct.
That is, since PKG_SYSREQS="false" is set by Rprofile, the user cannot override this setting and temporarily make PKG_SYSREQS="true" available by setting PKG_SYSREQS in an environment variable or Renviron, right?

[gaborcsardi]

I think it should only set it if it is not already set:

if (Sys.getenv("PKG_SYSREQS") != "") Sys.setenv(PKG_SYSREQS = "false")

The user or system profile can override it, I think, since it runs after this "internal" profile.

Thanks!

[eitsupi]

Thanks for merging.
Could you consider patch release?

[gaborcsardi]

Yes, we'll have one at some point, but a release is quite a lot of work.

If you need a quick workaround for the current release, you can use --without-sysreqs and set up the PKG_SYSREQS env var system wide.

Alternatively, for x86_64 Linux you can download a build from a nightly test artifact, e.g. https://github.com/r-lib/rig/actions/runs/6295783883

I see, thanks for your reply!
