build fix
In NetBSD 11 and possibly also SmartOS the ar 'l' modifier went from
l   This modifier is accepted but not used.
to
l   Specify dependencies of this library.
so ar clq went to "not working"; remove the l and reorder to
"command first, modifier after" and it'll build again.
Test-built on netbsd-11 and netbsd-10

icb: remove some warnings for NetBSD-current

Log message:
Fix MAKEFLAGS handling to work with spaces in UNPRIVILEGED_GROUPS

Let environment variables handling passing MFLAGS/MAKEFLAGS to children
rather than do it explicitly on the command line.  As of 1.24 of
mk/unprivileged.mk pkgsrc puts UNPRIVILEGED_GROUPS in MAKEFLAGS.
UNPRIVILEGED_GROUPS contains a space-separated list of the groups
the current account is a member of.  This requires proper quoting
in MAKEFLAGS if the current account is a member of more than one group
(due to the spaces), and the old version of Makefile does not take
that into account.
