svn commit: r347018 - projects/runtime-coverage-v2/share/mk

[Enji Cooper]

Author: ngie

New Revision: 347018
URL: https://svnweb.freebsd.org/changeset/base/347018

Log:
  Guard against cases where GCNOS would be empty, resulting in failed builds
  
  There are some Makefiles that install headers explicitly, without creating
  programs, e.g., `usr.sbin/amd/include`. In order to support this case moving
  forward, specifically test for _GCNO_SRCS being non-empty, then set GCNOS
  appropriately.
