Basically, the libc (and its headers) used for compilation needs to be
the same as on the target system, or older. So you should either use
the libc you just built along with the cross-compiler, or use your
target's headers to build with.

For static linking, -static is the most important part. libgcc is
another component handled specifically. To see if a program uses
dynamically linked libs, you can use the `ldd' program to see what's
dynamically linked by the dynamic linker. (Another way is to use
readelf or objdump so peek into the binary.)
