bitbake make-native; MACHINE=qemuarm bitbake icu would fail with: *** No rule to make target `uconvmsg/libuconvmsg.a(uconvmsg/uconvmsg_dat.ao', needed by `uconvmsg/libuconvmsg.a'. Stop which is caused by a bug in make 3.82 which the attached patch fixes.

* NEWS: Accidentally forgot to back out the sorted wildcard
|
|
enhancement in 3.82, so update NEWS.
|
|
Also add NEWS about the error check for explicit and pattern
|
|
targets in the same rule, added to 3.82.
|
|
|
|
* main.c (main): Add "oneshell" to $(.FEATURES) (forgot to add
|
|
this in 3.82!)
|
|
|
|
* read.c (parse_file_seq): Fix various errors parsing archives
|
|
with multiple objects in the parenthesis, as well as wildcards.
|
|
Fixes Savannah bug #30612.
