# Patch the executable from ELF OS/ABI type `Linux' (3) to `SVR4' (0).

# This doesn't seem to matter to ld-linux.so.2 at all, except that it
|
|
# refuses to load `Linux' executables when invokes explicitly, that
|
|
# is, when we do `ld-linux.so.2 $out/System/ut2004-bin', which we need

# to override the hardcoded ELF interpreter with our own.

# This is a horrible hack, of course. A better solution would be to
|
|
# patch Glibc so it accepts the `Linux' ELF type as well (why doesn't
|
|
# it?); or to use FreeBSD's `brandelf' program to set to ELF type
|
|
# (which is a bit cleaner than patching using `dd' :-) ).
