[Qemu-devel] [PATCH] Fix *-user build error

Currently building i386-linux-user fails with this error:

  CC    i386-linux-user/fpu/softfloat-native.o
[...]/qemu/fpu/softfloat-native.c:132:5: error: "HOST_LONG_BITS" is not defined
make[3]: *** [fpu/softfloat-native.o] Error 1
make[2]: *** [all] Error 2
make[1]: *** [subdir-i386-linux-user] Error 2
make: *** [build-all] Error 2

This trivial patch seems to fix it (without messing up the i386-softmmu
build, the other one I sort of tested). I assume it also fixes similar
errors in building the other *-user targets.

make distclean didn't help here (neither did "make clean", which is what
I used before submitting the trivial patch).

"rm */config.h" did work. Thanks.

Why doesn't "make clean" do what one expects it to do? Can't it be made
to behave properly?

I see. All that basically happened was that this rename etc. took place
in a repository in which I had previously built qemu and I should not
run into this issue anymore. Thanks.
