This did not work for me
because the make.cross script tries to download GCC 7.3.0 xtensa-linux
but it is missing in the web site.

$ GCC_VERSION=7.3.0 make.cross ARCH=xtensa
Cannot find xtensa-linux under
https://download.01.org/0day-ci/cross-package check
/tmp/crosstool-files


I installed xtensa-de212-elf-gcc by hand,
but I could not reproduce the error.


GCC_VERSION=7.2.0 make.cross ARCH=xtensa
worked, but I could not reproduce the issue either.
(the build terminated with a different error.)


Where can I see the full build log?
