Some gcc.target/i386 tests requires the mmap feature, but that's not
enough for the test to be able to call sysconf.
This patch introduces a sysconf feature, analogous to mmap, and adds
it to tests in gcc.target/i386 that call sysconf.
There are other tests within gcc.dg and g++.dg that call sysconf, but
I haven't added the tag to them, because they already cover it with
target triplets. I was a little nervous about dropping the triplets,
and saw how they implied sysconf, so I left those alone.
for gcc/ChangeLog
* doc/sourcebuild.texi (sysconf): New effective target.
for gcc/testsuite/ChangeLog
* lib/target-supports.exp (check_effective_target_sysconf): New.
