Putting tab first in IFS breaks func_echo_all usage of $*,
resulting in failure of func_infer_tag to match a command line using a
$CC with trailing spaces. The trailing spaces were stripped out of
CC_expanded but words in $CC were separated by tabs. This didn't
match the makefile expansion of $CC using the standard IFS with a
first char of space.
* gl/build-aux/funclib.sh (IFS): Make first char a space.
