Description:
------------
Commit 89d4217ed873aa9ed8bee1faf0d31bb52c911ae6 broke FreeBSD compatibility by using an array syntax not supported by the FreeBSD /bin/sh (which is not bash).

In line 193 of config9.m4 this line:

CURL_SSL_LIBS=()

is taken as a function definition by FreeBSD's shell, but functions may not contain = so it errors out during configure:

/tmp/pear/temp/pecl_http/configure: 5230: Syntax error: Bad function name




Test script:
---------------
Just run configure on FreeBSD.


Actual result:
