You're probably setting up your cross environment incorrectly which, 
unfortunately, is very common.

The proper thing to do is to have GCC use a different system include 
directory and a different prefix.  That will result in a directory where 
there are gcc binaries with normal names installed in ${cross_prefix}/bin

You need to build and install pkg-config to this prefix too, and then 
when it comes time to actually doing the QEMU configure, you should do 
something like:

export PATH=${cross_prefix}/bin:$PATH
export PKG_CONFIG_PATH=${cross_prefix}/lib/pkg-config:$PKG_CONFIG_PATH

Many automated cross compiler environment scripts will install specially 
named versions of gcc and binutils in your normal $PATH.  The trouble 
is, this is a bit of a hack and unless you know to make this hack work 
with other build tools, it all comes tumbling down.
