I see there was a second dlopen and this did indeed succeed; compile
successfully bulds and leaves the libcc1 directory. Following this I see build
fail while compiling in subdirectory "arm-linux-gnueabihf/libgcc". The command
line "make" shows this failure i libgcc:

The libgcc config.log shows what seems to be the implication of needing to look
at yet a different config.log, but the message does not provide any indication
of what really went wrong:

Which config.log is the message referring to? I did not see anything which
would indicate which subdirectory config.log would be relevant (and I see no
other errors which are obvious). Since the same host PC is building the same
Linaro software with config being almost identical to the aarch64 version, it
seems like the armhf sysroot has to be involved, but I've seen nothing to
narrow this down. Are there any suggestions on where to look or a hint of the
true cause of the armhf build error?
Thanks!_______________________________________________
