Subject: [PATCH] configure - m4: make CURL_CHECK_DEF ignore leading whitespace
 on symbol def

When using Sun C compiler the preprocessor somehow inserts an extra space
in front of replaced symbol, breaking CURL_CHECK_DEF macro. To workaround
this, macro CURL_CHECK_DEF now ignores all leading whitespace in front of
symbol substitution result.
