 I don't know. I don't see the string $NETBSDSRCDIR using readelf =
 --debug-dump
 in the files in /usr/libdata/debug on gcc-10.3 and gcc-9.3 systems and I =
 don't have
 anything older than that.  I guess one way to test is to break it on =
 purpose
 (i.e. change the .mk file to expand the variable instead of having gcc =
 do it,
 then check the reproducible builds website after a week :-)
 This is not the only patch that we have for gcc though: =
 --debug-regex-map is more
 complicated and still needed to handle OBJDIRs...
 
 	cvs diff -r FSF in /usr/src/external/gpl3/gcc/dist
 
 is instructive :-)
 
 A lot of that should be upstreamed...
