There is certainly potential here, but let me list why your method
will be flawed:

1) Non single user mode means you cant predict what deamon is doing
what at what time.
2) CFLAGS in make.conf are usually changed by users often. You need to
test against the age of /var/log/emerge.log and test against the
ebuild. Many ebuilds filter out several CFLAGS.
3) There's too many entries to fill in, prone to user error, false
assumptions and ofcourse the people that will just fill in junk for
the sake of it.

I think a much better solution is to make a script that will auto
reboot into single user mode, perform all tests, reboot into mult user
mode and upload results.

I could help write some of those tests and benchmarks.

I've worked on something similar earlier this year, but its really
quite a major, complicated task thats a lot harder to achieve than
just making a simple php page where people fill in values.

Thats why I suggested a performance forum, so things can be discussed
and polished before a good quality, comprehensive database can be
made.
