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.

configure.in: no pattern substitution

• configure.in: get rid of pattern substitution, which is not
  supported by ash, and ash on NetBSD parses whole source first
  and fails to start. [ruby-dev:48823] [Bug #10750]
