[how best to package a stub for which the cross-compiler isn't in Debian]
[possible solution 1]
1) Ship a built copy of the code in the package's .diff.gz, and DTRT
at package creation time to move the .bin from debian/ to the right
place in the staging tree. The source code for the .bin is in
.orig.tar.gz, under a free license. Anyone is free to modify or
rebuild the .bin, provided they obtain an arm7 cross-compiler by
non-debian means (instructions provided). People who just want to
rebuild the package can do so, without caring that there is
cross-compiled code involved.
Pro: dead simple, the packaging problem goes away. Con: means shipping
a binary blob in the source distribution, which appears to be frowned
upon, regardless of whether the source is also freely available in the
source distribution.
A slight variant on this would be to ship assembly source (the output of
gcc -S) instead of a binary blob, and cross-assemble that. If the stub
is 136 bytes long, assembly isn't too bad, and it's a step away from a
binary blob. This presumes that the cross-tools in Debian can correctly
assemble arm7, which I haven't verified.
But the binary-blob variant is probably simplest, and I'd recommend going
with that to get packaging done and the package in Debian. Alternately,
check for the compiler, and use it if it's installed. (And fall back to
the binary blob if it's not there.)
