This use of _SQ variant is fishy, isn't it? Judging from the output
of
$ git grep _SQ Makefile
e.g.
Makefile: $(INSTALL) $^ '$(DESTDIR_SQ)$(gitexec_instdir_SQ)'
Makefile: $(INSTALL) $^ '$(DESTDIR_SQ)$(gitexec_instdir_SQ)'
Makefile: $(INSTALL) $^ '$(DESTDIR_SQ)$(gitexec_instdir_SQ)'
I'd expect that any _SQ variant must be referenced inside a single
quote pair. In fact, that is why a single quote (and nothing else)
in the base variable is replaced with the magic "'\''" sequence,
first stepping out of the current sq context, append a single sq
(escaped with a backslash from the shell), and then stepping back
into another sq context.
I think nobody saw breakage only because they do not have two
consecutive SPs (or any single quote) in their path to $perllibdir.
If we depend on such limitation, there is no point using _SQ
variant, but we already have _SQ variant, let's use it correctly.
