Both are doing same thing in the end. if LIBS is altered we inject the compiler flags
same happens via LDFLAGS except that if we use LDFLAGS then we can utilize overrides
at recipe level and they are automatically exported into component Make systems.

LIBS is supposed to be computed during configure if one was to use libs approach
then USERLDLIBS is safer.

I guess what you might have seen is that there is no provider for libiconv-native
which is already fixed by
https://github.com/kraj/openembedded-core/commit/a5e6f5939c0ee4280eabd7cfc01131052040bc81

if it was something else. Please report with more details.
