[Spice-devel] [vdagent-win PATCH] Avoid using LTO by default during compilation

[Frediano Ziglio]

LTO option allows to have smaller executable stripping
unneeded part of code.
These options were added by a095f4806e ("build-sys: statically
build agent").
The gain of using these options currently are quite small,
from a small test:

$ ll *.exe
-rwxrwxr-x. 1 freddy freddy 506880 Jul 26 11:26 vdagent.exe
-rwxrwxr-x. 1 freddy freddy 198656 Jul 26 11:26 vdservice.exe

$ ll *.exe
-rwxrwxr-x. 1 freddy freddy 509952 Jul 26 11:26 vdagent.exe
-rwxrwxr-x. 1 freddy freddy 200192 Jul 26 11:26 vdservice.exe

Considering that there are some bug in some recent MinGW distributions
like https://bugzilla.redhat.com/show_bug.cgi?id=1475237 and
the small gain I would disable these options.
