configure: Find SpiderMonkey with pkg-config only
Don't search for SpiderMonkey in hardcoded directories (/usr /usr/local /opt/spidermonkey /opt/js), and don't support --with-spidermonkey=DIR (which I think was documented in elinks-users only). Instead, ask pkg-config for mozjs185 or mozilla-js. Everyone who installed SpiderMonkey in an unusual place must set PKG_CONFIG_PATH appropriately. This commit also includes a few minor changes in the SpiderMonkey section of the configure script: * Update the SpiderMonkey version number in "checking" messages from 1.5 RC3a to 1.8.5, which matches the actual checks. * Wrap the option documentation with AS_HELP_STRING. * Use the Autoconf-generated $with_spidermonkey variable directly, instead of copying $withval. * Quote the arguments of macros more consistently. * Warn if SpiderMonkey was requested but not found.
