The build directory structure has nothing to do with where the binaries
are installed. I'll send you (and jdp and peter) details of an alternative
makefile design that treats the architecture specific makefiles as
additive rather than exclusive [Sorry to sound like Terry 8-) ] so
that more than one architecture is built.
Apart from gas which is a special case, the other binutils can be
built on the host architecture with additional architecture support
by adding something like this (example for i386 and m68k on alpha) in
/etc/make.conf:
---
# Architectures for which cross tools are required:
CROSS_TOOLS= i386 m68k
---
After the make world, I get one each of:
addr2line ar ld nm objcopy objdump ranlib size string strip
to run on the (alpha) host plus an `as' for the host, and an as_${arch}
for each additional architecture specified in CROSS_TOOLS.
The makefiles aren't that bad - just different. And I'm not talking about
aout support that is covered by usr.bin/ar, usr.bin/ranlib, etc. Those
tools can stay as they are. Nothing lost, nothing gained. 8-)
Also bear in mind that the only tools you are installing in
/usr/libexec/elf are ar, as, ld and ranlib. The other tools are
being installed in /usr/bin.
