Subject: [PATCH] perf build: Do not fail on missing Build file
|
|
|
|
Allow nesting into directories without Build file. Currently we force
|
|
include of the Build file, which fails the build when the Build file is
|
|
missing.
|
|
|
|
We already support empty *-in.o' objects if there's nothing in the
|
|
directory to be compiled, so we can just use it for missing Build file
|
|
cases.
|
|
|
|
Also adding this case under tests.
