Replace egrep with grep -E in Makefile

[stevefalco]

Fedora 40 gives deprecation warnings on the use of egrep. Replacing "egrep" with "grep -E" in the Makefile is functionally equivalent and eliminates the warnings.

That's a good idea. However, would you mind adding a line like EGREP ?= grep -E with the others near the top, and use that in the check-dirs target? No need to make a new pull request, you can amend the commit and force push to update this pull request.

Done. Thanks for the suggestion. I made a similar "egrep => grep -E" change for the ka10-simh and simh repos (in file sim_ether.c) and created PRs for them upstream. Those projects don't use the same override mechanism, though, so I just made the changes directly. Please let me know if you'd like a different approach for that. I believe you control ka10-simh but I don't know if you have commit rights on simh, BTW. The only other change I have outstanding is in pdp6 to fix a compile error - I had announced that one a week or two ago, and I've requested it to go upstream: aap/pdp6#32 Steve

Thanks, this looks good now!
