I'm installin Python 3.91. on a Solaris 10 system (I known it's 'old' but I have a legacy installation to support).

Running ./configure the following errors are seen...

checking PROFILE_TASK... -m test --pgo
checking for --with-lto... no
checking for llvm-profdata... no
grep: illegal option -- q
Usage: grep -hblcnsviw pattern file . . .

Paul, please take a look. You added the code in commit 62972d9d73e.

This particular grep statement is used to validate the `tzpath` variable. Apparently it is easy enough to achieve what I was going for using vanilla grep with no options, so I've created GH-24200 to fix the issue.

I notice that there are other uses of `-q` and `-E` in the configure file, but presumably those are on more optional paths.

@martin.wheatley.home: Can you check to see if GH-24200 fixes your issue?

Also, can you clarify whether this happens with a plain `./configure` invocation, or are you specifying `./configure --with-tzpath='/usr/share/zoneinfo:/usr/lib/zoneinfo:/usr/share/lib/zoneinfo:/etc/zoneinfo'` yourself?

I'll do the test

it happens with a plain ./configure

Many thanks
Martin
