Subject: [Qemu-devel] syscall uname fix.

Hi All,
In my continued quest to get Gentoo to install under qemu-arm, I ran into a
problem with configure:
checking build system type... configure: error: cannot guess build type; you
must specify one
With that info I tried uname -m and found it reporting i686. Looking at
linux-user/syscall.c under TARGET_NR_uname, an effort is made to copy
UNAME_MACHINE into the utsname structure, and then for some reason sys_uname
is called again, overwriting that change. The following patch fixes that.
configure now is able to determine the build system type and it looks like
gentoo may now install.
