guile-3.0 fails to cross build in a very funky way. Have a look at the
log:

Notably, /usr/include/string.h includes guile's strings.h. A system
header should not be including a package header. It also is a cross
build specific problem as it builds fine natively. The problem is rooted
in the "if [ "yes" = "yes" ]" branch earlier where one of those "yes"
actually is "$cross_compiling". The cross branch sneaks in an additional
-I. which causes the guile strings.h header to be picked up at the wrong
time. I'm attaching a patch for your convenience.
