Bug #10750: configure script has bashism on Ruby 2.2.0

----------------------------------------
On Ruby 2.2.0, configure script has bashism part and it cause syntax error:

~~~
./configure: 21262: Syntax error: Bad substitution
~~~

The problem line:

~~~
	  test "x${linker_flag}" = x || flag="${linker_flag}${flag// /,}"
~~~

`${flag// /}` is not portable syntax but bash specific syntax.

The problem dose happens on NetBSD 7.0_BETA and current (7.99.4), but not on NetBSD 6.1_STABLE.
So, it might be some bug or syntax change on NetBSD.

Anyway, I do not think it is good idea to use none portable shell syntax.
