Configure: postpone running the test binary.

Previously, the ./configure script would attempt to execute the test
binary during the C compiler check, and it would abort with an error
saying that the compiler doesn't work if there was any issue running
the test binary (e.g. due to missing compiler and/or linker flags).

This change delays that check and runs the test binary compiled with
all provided compiler and linker flags.
