This was removed in GnuTLS 2.8.0:

You need to disable linker maps with
  LINKER_MAPS =
We restrict libc versioning to Solaris 10u8 if possible, but gnutls needs
a newer libc.

-R is passed via LD_OPTIONS through the environment, you need to look in the
command invocation or „mgar modenv“.

Essentially this is similar enough to
  https://buildfarm.opencsw.org/source/xref/opencsw/csw/mgar/gar/v2/gar.lib.mk#834
that it should work. Just add the linker map removal and try again.
