[BRLTTY] Nits in configure.ac

[Stepan Kasal]

Hello,

when reviewing a packaging issue in Fedora GNU/Linux, I noticed a nit
in your Autoconf usage.
Your configure.ac uses changequote(), which is not recommended by the
Autoconf manual and clutters the code.
It's much safer and nicer to use quoting: when a string is inside a
pair of brackets, it's not expanded by m4.

So I suggest to apply the patch attached to this mail.

Thanks for your time,

	* configure.ac: Use quoting, not changequote().
