[libvirt] [PATCH 2/2] build: relax the relaxed stack frame limit further
Pick 256k as the limit.
While -Wno-frame-larger-than would make more sense for usage
in our test suite, the -Wno version seems to have no effect
if -Wframe-larger-than was already specified.
Use an (un)reasonably large value instead.
Fixes the build with clang:
../../tests/cputest.c:964:1: error: stack frame size of 33176 bytes
in function 'mymain' [-Werror,-Wframe-larger-than=]
mymain(void)
^
1 error generated.
