[Qemu-devel] [PATCH] configure: replace \n with space in optarg

[Hu Tao]

When optarg happens to contain \n like:

../configure --target-list='i386-softmmu
 x86_64-softmmu'

make will fail with message:

config-host.mak:45: *** missing separator.  Stop.

This patch fix this problem by replacing \n with space in optarg.
