Two choices:
1) try to find an alternative. If there's none, fail.
2) make the corresponding asm or asm/arch branch available (non-trivial
and maybe not desirable)

Depends on your distribution: if it doesn't install any kernel-specific
headers, you wouldn't be able to compile programs requiring anything
beyond what it provided by your libc. Otherwise, there could be a
default location (such as /usr/src/linux is a default location now).

The main advantage of a script would be that one could easily compile
for multiple kernels, e.g. with

export TARGET_KERNEL=2.0.4
make

Even if your system is running 2.4.13-test1.

The architecture could be obtained from the tree or the tree could be
picked based on the architecture. This is a policy decision that could
be hidden in the script.
