configure: improve the header and library function checks

The project is often cross-compiled for embedded systems with all kinds
of wonky toolchains so update configure.ac with checks for less standard
functions and headers. While at it: rearrange the existing checks a bit
so that we only check for headers and symbols when we need them for
current build configuration.
