shell wrappers: merge -l nameoflib into a single -lnameoflib

[Ryo ONODERA <ryo_on%yk.rim.or.jp@localhost>]

Hi,

I am working on pkgsrc/lang/rust on NetBSD and Linux.
The older shell wrappers cannot handle "-l m" (whitespace between -l
and library name, m) and I cannot build some libraries in lang/rust.

I suggest the following patch.
It does not break

BUILDLINK_TRANSFORM=	l:execinfo:execinfo:elf

like BUILDLINK_TRANSFORM.

What should be confirmed to adopt this change?
