build: support cross compiling.
Check for cross compiling. If cross compiling, build stage1flex using a
custom link command.
We also override LDADD since that adds the replacement implementations
that are cross compiled, and instead always use the replacement library
implementations.
We don't use BUILD_OBJEXT and BUILD_EXEEXT since it seems that automake
does not support these.
Fixes #78.
