[libvirt] syntax-check Argument list too long problems

[Roman Bogorodskiy]

Hi,

Not so long ago I've started encountering issues with syntax-check, for
example:

trailing_blank
/bin/sh: grep: Argument list too long

When I'm running it with SHELL='sh -x' I can see that it's indeed trying
to run grep with really long list of files, e.g.:

+ grep -nE '\<error *\([^"]*"[^"]*[a-z]{3}' .ctags .dir-locals.el ...

and many many other files in the list.

I see this problem on FreeBSD, but not on Linux, I guess that's because
ARG_MAX is much lower on FreeBSD:

freebsd$ getconf ARG_MAX
262144
linux$ getconf ARG_MAX
2097152

It looks like it's not possible to change ARG_MAX value on FreeBSD. Do I
get it right that it's something that I need to report to gnulib?
