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.
