I sometimes get the following error when I build GhostPDL (complete build log: http://pkg.triaxx.org/pub/pkgsrc/reports/NetBSD/amd64/9.2/20211230.2208/ghostscript-agpl-9.55.0nb1/build.log):

gmake[2]: *** [base/unix-dll.mak:198: sobin/gsc] Error 1

I sometimes also get the following error:
ld: ./soobj/dxmainc.o: file not recognized: file truncated

The incriminated target is in base/unix-dll.mak:

$(GSSOC_XE): gs-so-links-subtarget $(PSSRC)dxmainc.c $(UNIX_DLL_MAK) $(MAKEDIRS)
  $(GLCC) $(GLO_)dxmainc.$(OBJ) $(C_) $(PSSRC)dxmainc.c

This error does not occur each time. But it is really annoying when it occurs during the building of a large set of packages since it is a dependency for a lot of packages.
