This is the first use of $glusterfs. Please define the default value,
the rationale is given at the start of configure:
# Default value for a variable defining feature "foo".
# * foo="no" feature will only be used if --enable-foo arg is given
# * foo="" feature will be searched for, and if found, will be used
# unless --disable-foo is given
# * foo="yes" this value will only be set by --enable-foo flag.
# feature will searched for,
# if not found, configure exits with error
I think "" would match other features.
