Subject: [PATCH] Adapt Configure to GCC version 10

I got a notice from Jeff Law <law@redhat.com>:

Your particular package fails its testsuite. This was ultimately
    tracked down to a Configure problem. The perl configure script treated
    gcc-10 as gcc-1 and turned on -fpcc-struct-return. This is an ABI
    changing flag and caused Perl to not be able to interact properly with
    the dbm libraries on the system leading to a segfault.

His proposed patch corrected only this one instance of the version
mismatch. Reading the Configure script revealed more issues. This
patch fixes all of them I found.
