[Bug 50811] gdi32.res fails to compile when freetype pkg-config cflags contain "-pthread"

[WineHQ Bugzilla]

--- Comment #3 from Rafał Mużyło  ---
I suspect the correct question here is: would you check output of 'pkg-config
--cflags glib-2.0' ?

That new part comes likely from glib being built with sysprof support (more
exactly - being linked with sysprof-capture static lib (as that lib is static
only)).

This would have likely affected gstreamer too, but the relevant macro in
configure.ac filters that out.
