- respect DEBUG_FLAGS rather than DFLAGS, currently any flag (e.g. `-ggdb3')
in DEBUG_FLAGS or CFLAGS is being overriden by DFLAGS' `-g'
- use PTHREAD_LIBS instead of -lpthread
- no need to specify -lc when no -nostdlib is used
- make build target verbose, options target doesn't show what flags are used when linking
- make install target verbose, so the user know what's being installed
- use CFLAGS when linking, too; makes things like -flto in CFLAGS work
- add extra tab to MAN1 (cosmetic)
