This change replaces the msleep with a wait for completion that the

assert the interrupt line after the final frame, in testing this meant that

x86-64, build: Fix stack protector Makefile breakage with 32-bit userland
If you are using a 64-bit kernel with 32-bit userland, then
scripts/gcc-x86_64-has-stack-protector.sh invokes 32-bit gcc
with -mcmodel=kernel, which produces:
<stdin>:1:0: error: code model 'kernel' not supported in the 32 bit mode
and trips the "broken compiler" test at arch/x86/Makefile:120.
There are several places a fix is possible, but the following seems
cleanest. (But it's minimal; it would also be possible to factor
out a bunch of stuff from the two branches of the if.)
