Remove FORCE from the list used by if_changed and friends. Otherwise the target will always be considered out of date when built with make 3.82.

Linux fixed this with commit 4f1933620f57 ("kbuild: change kbuild to not rely on incorrect GNU make behavior"). Similar to Linux, klibc if_changed already excludes $(PHONY) from $? when determining if a target is up-to-date. Klibc also has a $(PHONY) list of phony targets. But klibc does not add many .PHONY targets to $(PHONY). Changes in this patch: - add previously defined .PHONY targets to PHONY, so existing if_changed filtering app...

Hi Peter & others. Here are three patches that does the following: #1 - Update kbuild part of klibc so make clean works Adds gzip including a sample kbuild file #2 - Factor out definition of usr/ to two variables #3 - Move kbuild files to reflect location in the kernel As requested in earlier mail I need a bit of guidiance of what you expect from the kernel integrated parts of klibc.

Later upstream versions of mktokens create two files, so there will be no reasonable way to redirect its output. The if_changed macro assumes that the rebuild command does not change the current directory, which is why out-of-tree builds broke here prior to commit 984d40b0fc4c. Since we do need to change the current directory, do it in a subshell which won't affect the following commands generated by if_changed. Sig...
