No, it appears to just be compiling a lot more than in the past.

$ grep Compiling main.log-meson  | wc -l
5468

$ grep CC main.log-config  | wc -l
4855

This seems to be caused my compiling lots of stuff under tests/
that we did not previously build

$ grep Compiling main.log-meson  | grep tests/ | wc -l
616


not sure if this is specific to FreeBSD, or whether we're doing
this on all platforms and merely noticed first on FreeBSD due
to the timeout.

Mostly it seems to the libtestfloat ad libsoftfloat, but also
a bit of libqtest stuff.

Daniel
