description:
Add a mini-framework to centralise the handling of "hacks" for getting
particular packages to compile correctly. bsd.hacks.mk auto-includes
the hacks.mk file in the current directory. An example hacks file:
-------------8<-------------8<-------------8<-------------8<-------------
.if !defined(FOO_HACKS_MK)
FOO_HACKS_MK= defined
### [Sun Nov 14 02:08:31 EST 2004 : jlam]
### arm GCC 2.95.x optimisation bug tickled when compiling
### lib/funkyfile.c. Require a more recent version of GCC as a
### workaround and patch lib/funkyfile.c (patch-ae).
###
.if !empty(MACHINE_ARCH:Marm*)
PKG_HACKS+= optimisation
GCC_REQD+= 3.0
.endif
.endif # FOO_HACKS_MK
-------------8<-------------8<-------------8<-------------8<-------------
The comment which heads each individual hack should timestamp when the
hack was added and describe the bug that requires the hack. By
separating out hacks to a separate file, we should be able to simplify
package Makefiles so that they are more readable.
