*	bfstd: New sysoption() macro to check for POSIX option runtime support	Tavian Barnes	2024-08-09	1	-7/+17
\| \| \| \| \| \| \| \| \| \|	POSIX allows optional features to be supported at compile time but not necessarily at run time by defining _POSIX_OPTION to 0 and requiring users to check sysconf(_SC_OPTION) > 0. The new sysoption() macro simplifies the check. sighook() and bfs_spawn() now check for conditional runtime support for the relevant POSIX options.
