bug#28920: Cross compilation fails

[Ben Gamari]

While attempting to cross-compile guile for Linux on ARM from Linux on
amd64 I'm seeing the following error,

$ ./configure --disable-static --disable-dependency-tracking 
--build=x86_64-unknown-linux-gnu --host=arm-unknown-linux-gnueabihf 
--target=arm-unknown-linux-gnueabihf 
GUILE_FOR_BUILD=/nix/store/3a8vr1p51dnpz3rdpiq5kccl4cima9xs-guile-2.2.0/bin/guile
 CC_FOR_BUILD=gcc
$ make -j16
