  The build system isn't really set up to do cross-compilation.

  That helps.

  You're running the local "gcc", and not the cross-compiler.

  You should do:

$ CC=/path/to/cross/cc ./configure ... args ...
$ gcc scripts/jlibtool.c -o build/make/jlibtool
$ make

  That lets you build jlibtool with the native C compiler, and the rest of the build system will then use the cross compiler.
