General rule of thumb with anything Autoconf-related: always quote
everything. Therefore, better to say:
PKG_CHECK_MODULES([PKGNAME], [glib])
AC_SUBST([PKGNAME_CFLAGS])
AC_SUBST([PKGNAME_LIBS])
It doesn't matter until one day it does and you get bizarre and obscure
error messages and corrupted shell scripts and spend hours trying to
figure out why.
