All:
Is there a method to indicate to the bootstrap process that there
are includes ( such as sys/cdefs.h ) in a slightly non-standard
location? I have a Debian system on arm7 and for reasons yet obscure
there are no symlinks in /usr/include/sys that point to
/usr/include/arm-linux-gnueabihf/sys/ which is what I would expect for
the libc6-dev
package on Debian. Certainly such symlinks do exist on x86_64 thus :
root@nix:~# ls -lapb /usr/include/sys/cdefs.h
lrwxrwxrwx 1 root root 31 Dec 5 18:50 /usr/include/sys/cdefs.h ->
../x86_64-linux-gnu/sys/cdefs.h
However the arm7 pkgs do not exist for such a thing :
arm7$ uname -a
Linux arm7 4.4.132+ #1 SMP Tue Oct 23 18:03:49 CST 2018 armv7l GNU/Linux
arm7$ ls /usr/include/sys/
capability.h
arm7$
arm7$ ls -lapb /usr/include/arm-linux-gnueabihf/sys/cdefs.h
-rw-r--r-- 1 root root 15651 Jan 14 2018
/usr/include/arm-linux-gnueabihf/sys/cdefs.h
arm7$
Great.
Doing something like CPPFLAGS=-I/usr/local/include
-I/usr/include/arm-linux-gnueabihf doesn't work and the process blows up
fast like so :
/bin/bash ./libtool --tag=CC --mode=compile /usr/bin/gcc

So that is annoying.
If I do nothing special at all then I get sys/cdefs.h not being found :

So then ... manually make the symlinks one at a time and watch for
failures? Curious if anyone else has seen this sort of thing.
