Hi

I did some comparisons running sysinfo 5 times for each test with one compl=
ete
restart of fs-uae in between. Here's what I got:=20

68040/040 sysinfo test, fs-uae compiled with clang, 13-CURRENT amd64
Dhrystone 72223, 69189, 75229, 75808, 76020

68040/040 sysinfo test, fs-uae compiled with gcc7
Dhrystone 92611, 92801, 92660, 92489, 90485

If there are no objections, I think we should switch over to compiling the =
port
with gcc.

NOTE: These tests were done on fs-uae 2.9.7 but I've confirmed similar
differences with 2.8.4.
