This appears to only be a problem when using arm as a target

Reproducible: Always

Steps to Reproduce:
1. edit to include arm QEMU_SOFTMMU_TARGETS="arm"
2. emerge =app-emulation/qemu-kvm-1.1
3.
Actual Results:  
see description for error

Expected Results:  
compile successfully

The subject of your bug should include the full package name (app-emulation/qemu), possibly with the version number (app-emulation/qemu-1.0.1) not just `qemu`.

Regarding the bug, see [1], which provides a patch fixing what seems to be your error.

[Comment 2 Alexandre Borges Marcelo 2012-07-17 16:43:33 UTC]

I can confirm that app-emulator/qemu-kvm-1.1.[01] fails to build for the following softmmu targets: alpha arm m68k mips mips64 mips64el mipsel ppc ppc64 ppcemb sh4 sh4eb sparc64. 
The patch from Comment 1 resolved the issue, although I only tested if the package compiled.

1) Please post your `emerge --info' output in a comment.
2) Please attach the entire build log to this bug report.

It seems that this problem has already been discussed and solved in qemu-kvm upstream. A patch can be found here:

https://git.kernel.org/?p=virt/kvm/qemu-kvm.git;a=commit;h=bbf3b80401d55ac3339160cefa17f0015317f512

(worked for me)

Just found out this is a duplicate of bug 425418.
