Rework build system v2 (#71)
* Remove non-POSIX extensions and commands * Drop autodetection in favor of OPT_DEP_DEFAULT * Use += for LDLIBS as some BSD distros need to add extra flags * Change DOCPREFIX -> EGPREFIX * Use ?= for MANPREFIX and EGPREFIX * Update docs With this, we should have a stable build system. No further significant changes should be needed.
