gcc5 unusable in trace mode

[chrstphrchvz (Christopher Chavez)]

Edit: ticket was originally for mysql8, but other simpler ports (e.g. pv) appear to be affected.

Using compiler.whitelist macports-gcc-5 to force compiling with gcc5, a port fails to configure/build using trace mode. Example with mysql8:

main.log for configuring with tracemode

[kencu (Ken)]

maybe first try to build anything with gcc5 to see if it is totally busted on whatever OS you're on here.

[chrstphrchvz (Christopher Chavez)]

gcc5 seemed to work without trace mode (see #60894). However trying to compile another simple port pv in trace mode fails, so this issue might indeed have nothing to do with mysql8. I'm not sure if this issue is in gcc5 or possibly in trace mode itself (base).
