autoconf: improve handling of versioned symbols

Browse Source 
It checks whether versioned symbols should be enabled before checking
whether it is possible (i.e. the linker supports --version-script) or
not. This avoids a useless warning when building cURL on a platform that
does not use GNU ld.

Moreover, it fixes broken indentation of this chunk of code.
