[PATCH 2/2] lib-symbol-versions: fix m4 quoting

[Eric Blake]

* m4/ld-version-script.m4 (gl_LD_VERSION_SCRIPT): Use correct
format for AC_LINK_IFELSE.

Last one, at least according to an autoconf run on:

gnulib-tool --create-testdir --dir=t $(gnulib-tool --list)

as that was faster than waiting for --create-megatestdir to complete
(but, I'm still running the megatestdir, since it found the btowc
issue, and may find others).

Hmmm - this is the first time that AC_LANG_SOURCE was already there,
but it was underquoted (that is, it was expanded too early, so the
witness macro was lost by the time it was inside the AC_LINK_IFELSE).
I'm betting that autoconf 2.68 will flush out a lot of packages with
insufficient quoting ;)
