Some syntax-check rules use GNU sed specific regexps, so allow
to override which sed would be used to fix 'syntax-check' for
non GNU-userland systems.

[Adding bug-gnulib]
Hmm - this is an interesting situation. I imagine we will probably hit
cases where maint.mk also starts assuming GNU sed, so it becomes a trade
of whether it is easier to rewrite the expressions to portable sed that
works out of the box on BSD, or to rewrite the rules to use $(SED)
uniformly. And what happens if we use $(SED) but the configure.ac did
not request AC_PROG_SED in configure.ac? (In gnulib, m4/po.m4 requires
AC_PROG_SED, which means any package using gettext is safe, but we'd
have to hoist the requirement of AC_PROG_SED into gnulib's gl_INIT macro
if we wanted to work even for packages that don't use gettext).

Is the non-portable sed usage merely the fact that I used \+ here? If
so, \{1,\} is a more portable way to write the 1-or-more modifier.

POSIX has decided to add support for 'sed -E' in a future version (GNU
sed supports that as an alias for 'sed -r', the alias has been around
for a long time, but was only recently documented as a result of the
POSIX decision):
http://austingroupbugs.net/view.php?id=528
Would using 'sed -En -e ...' fix it for you? Or should we just rewrite
this in basic rather than extended regex:
-e /\(xenapiSessionErrorHandler\|vah_\(error\|warning\)\)/d'
-e /\<$func_re)
*([^"*"\([^%"]\|"\n[^"\*"\)*"[,)]/p'

And this one's portable as well. Or is the idea to replace ALL use of
s/sed/$(SED)/ even where it makes no difference? If so, we should
probably also do it in maint.mk. I'd like some feedback from the gnulib
community if favoring $(SED) is the right thing to do, or if I should
just rewrite libvirt's rules to stick to portable sed constructs.

My kneejerk reaction is that we'd probably have fewer problems using
'$(SED)' everywhere in a makefile, rather than using '$(SED)' some
places and 'sed' in others, because it'd be one less 'sed'
implementation to worry about.

Yes, that was the idea. That's why I replaced all the usage of 'sed' even
though not all of them are non-portable, as Eric pointed.
For sure, using portable regexps is better way, but I don't know how
much of effort that would be.
