Ah that will probably be the problem - config/script/switch-arch
contains the logic which detects how
NATIVE_BITWIDTH_EQUALS_HOST_BITWIDTH and SWAP_ENDIANNESS should be set
and adds them to CFLAGS in Makefile.target as appropriate.
OK. I'll start looking to see how to change that for by build
environment.
Great - thanks!
I figured it out!
/bin/sh, the default choice if you just run switch-arch, on OpenSolaris is
ksh93, which silently fails on the $...bigendian tests. If I run switch-arch
with /usr/xpg4/bin/sh or bash, it works fine and my builds from x86 and
sparc are now correct and load. It looks like testing for $KSH_VERSION would
be a way to find out if the shell isn't going to work, but I don't know if
this would come up enough to warrant adding logic to check it.
Maybe we have a bashism somewhere (should be fixed), or more likely
since ksh93 is not fully Posix compatible, we use some Posix features
which are not implemented by ksh93 (maybe avoidable). Please send
again the output from sh -x for the bigendian test.
As run on my Ultra60 which should set CONFIG_BIG_ENDIAN:

crosscflags()

-    local target=$2

This happens to work because variable $target (used in some for loops)
is not used after the call to crosscflags. It's a bit fragile though.
Considering the various uses of $target, I'd rename $host to $host_cpu
and $target to $target_cpu in crosscflags.
