Revision da750b15c0e69f809243d56eceb37d56a8fc9cfd authored by Richard Levitte on 18 May 2021, 16:22:57 UTC, committed by Richard Levitte on 19 May 2021, 17:04:06 UTC
Make apps/progs.pl not look at apps/progs.c
apps/progs.pl will have apps/progs.c as output, and on some systems,
the output file of a program is locked against reading.
Unfortunately, apps/progs.c is also part of the sources that make up
apps/openssl, so it's necessary to mark that file in a way that makes
progs.pl skip over it.

Fortunately, this is easily done with a special attribute in
apps/build.info and a simple adaptation of apps/progs.pl.
