>Description:
Attempting to build www/webkit-gtk 2.34.3 (as currently defined for
both pkgsrc 2021Q4 and -current) on NetBSD 9.x stable branches fails.

An example can be found here:
http://victory.netbsd.org/pkgsrc/packages/reports/2021Q4/amd64-9.0/20220103.0714/webkit-gtk-2.34.3nb1/build.log

It fails like so:

[ 20%] Linking CXX executable ../../bin/WebKitWebDriver
ld: CMakeFiles/WebDriver.dir/Session.cpp.o: in function `WebDriver::Session::setInputFileUploadFiles(WTF::String const&, WTF::String const&, bool, WTF::Function<void (WebDriver::CommandResult&&)>&&)':
Session.cpp:(.text+0x180f3): undefined reference to `WTF::FileSystemImpl::fileExists(WTF::String const&)'
gmake[2]: *** [Source/WebDriver/CMakeFiles/WebDriver.dir/build.make:281: bin/WebKitWebDriver] Error 1
gmake[1]: *** [CMakeFiles/Makefile2:1615: Source/WebDriver/CMakeFiles/WebDriver.dir/all] Error 2
gmake[1]: *** Waiting for unfinished jobs....
[ 20%] Building CXX object Source/JavaScriptCore/CMa

I can reproduce this in my own build environment running 9.2_STABLE. (I
can, however, successfully build this package on 9.99.93 as of last
week.)
>How-To-Repeat:
(As above.)
>Fix:
Unknown, I haven't looked into it.
