Remove Unnecessary Variables

In your custom board's scripts/Make.defs file, It is no longer necessary to define the following variables unless your build requires that you assign special values to them:

• DIRUNLINK
• MKDEP
• ASMEXT
• OBJEXT
• LIBEXT
• EXEEXT

These variables have been refactored into tools/Config.mk.

See these git commits in the main NuttX repository:

• 9ec9431706fd0eb7c4c4410d84dafff68ff31366 (DIRLINK and DIRUNLINK)
• 8b42ee421a41214093c0238e479d73a1099b0e82 (MKDEP)
• 567962bd6263bf8809fb63c739f6ec668c69c416 (ASMEXT, OBJEXT, LIBEXT, EXEEXT)
