In 'g' shell script, we use grep to get substring from config_host.mk file.
When config_host.mk file contains non-ascii characters(e.g. Japanese),
this processing doesn't work.
As a result, some variables(SUBMODULES_CONFIGURED, REFERENCED_GIT, LINKED_GIT) will be
assigned to "Binary file (standard input) matches".
This is an error message of grep.
The problem will reproduce on Cygwin64 with Japanese locale.

With '-a' option, grep will work well, and 'g' shell script will work correctly.
