options: properly compare string arguments

Similarly to 7f967bd2a7ba156ede3fbb147e66dea5fb7137a6, we need to
compare string with strcmp.

strcmp.

So it's caused by PCH:

Good, I placed a couple of '#include ' and I can reproduce it now.
Thanks for the report.

Right - that's the Qt bug I'm hoping to fix, but I don't get far because of the
ICE. :) The libstdc++ headers have been reorganized, so Qt's expectations that
numeric_limits is available without including  are no longer valid with
GCC 11.

Yeah, I fed that output to g++, and then it compiles just fine. But when it's
in the actual build with all the -MD -MT -MF flags, it doesn't. Those are, btw,
in case it's of any help,
-MD -MT qtbase/qmake/CMakeFiles/qmake.dir/__/src/corelib/global/qendian.cpp.o

..or maybe I'm just too dumb to invoke g++ -E properly, and the rest of the
options confuse the compiler.

The output of gcc -E for this build is empty, so sure looks like the crash
is in the preprocessor.
