You should at least change the PATH to include where the cross-compiler 
is (if you are using MokoMakefile/OE/bitbake, check one of the 
build/tmp/work/*/*/temp/run.* files for a good value for PATH). If that 
isn't enough for configure to autodetect the cross-compiler, you might 
have to pass CC=, LD=, and so on to configure (but I'd try without them 
first, hoping configure is smart enough to try to call $(HOST)-gcc first 
before trying gcc).
