In Nettle's Makefiles, CC_FOR_BUILD is intended to be a compiler targetting the *build* system, used to compile things like eccdata.c that are run on the build system as part of the build. It's intended to be different from CC when cross compiling. Not entirely sure how CC_FOR_BUILD is used in config.guess, but I think it is used to detect the system type of the build system. > There is nothing specific in the output of powerpc64-openwrt-linux-musl-gcc > -E -dM log as I can see. In musl libc FAQ, they stated that there is no > __MUSL__ in the preprocessor macros https://wiki.musl-libc.org/faq.html The interesting thing I see is #define _CALL_ELF 2 I hope this can be used to distinguish from other big-endian systems, that use ELFv1 abi?
