So this really honestly is a toolchain problem, not a driver problem.
Neither icecream nor gcc are broken.
The solution is pretty simple:
====================================
Never ever include -v or --verbose in CFLAGS
====================================
Why?
Because otherwise there will be some output to
stdout during the -fPIC test compile executed from
configure, and that output causes the build system
to erroneously assume that -fPIC does not work.
Hence xorg parts that normally would be build with
-fPIC will be built without that flag.
autoconf bug! Nice find.
I think the test for "-fPIC" support is fundamentally
broken and should be fixed. Or would it be better
to check for -v and --verbose in CFLAGS?
It sounds like the test is broken, yeah. Although I wonder how many
other standard autoconf tests have this property.
