### Rationale for this change We can get into a broken state with a working test compile in `nixlibs.R` but empty `PKG_LIBS` when pkg-config fails to find some libraries (e.g. libcurl on mac due to missing system stubs) in `configure`. This leads to a failed test compile in configure with pc errors silenced. ### What changes are included in this PR? Catch this and rerun the pkg-config-less library detection that should fix this in most cases. ### Are these changes tested? locally and on cran (where this error first surfaced) -- This is an automated message from the Apache Git Service.
