>Description:
Wanting to build an updated kernel and cross-compilation toolset, using build.sh on my Opteron server (running Solaris 10), I have errors, that I believe stem from the recent libc/kernel endianness tweaks:

./build.sh -m sparc64 -T ${MYTOOLS} tools kernel=GENERIC

gives this error:

#   compile  compat/rmd160.lo
gcc -O  -I. -I./include -I/home/garrett/netbsd/src/tools/compat -DHAVE_NBTOOL_CONFIG_H=1  -D_FILE_OFFSET_BITS=64 -D__DBINTERFACE_PRIVATE -c -o rmd160.lo.o    /home/garrett/netbsd/src/tools/compat/../../lib/libc/hash/rmd160/rmd160.c
/home/garrett/netbsd/src/tools/compat/../../lib/libc/hash/rmd160/rmd160.c:37:28: machine/endian.h: No such file or directory

*** Failed target:  rmd160.lo
*** Failed command: gcc -O -I. -I./include -I/home/garrett/netbsd/src/tools/compat -DHAVE_NBTOOL_CONFIG_H=1 -D_FILE_OFFSET_BITS=64 -D__DBINTERFACE_PRIVATE -c -o rmd160.lo.o /home/garrett/netbsd/src/tools/compat/../../lib/libc/hash/rmd160/rmd160.c
*** Error code 1


>How-To-Repeat:
On a Solaris 10 machine, just try to bootstrap the tools.
>Fix:
Somehow, machine/endian.h needs to be a valid include location, so either arguments to the compiler, or a cross-compile environment where machine/endian.h is made to be sane.  Cross-compilation is *supposed* to work.  This will ultimately eventually become a show-stopper for me, as I have to use this system to cross compile for environments that cannot self-host (e.g. evbmips).
