Subject: [PATCH] build: make _make_dirs robust against too long argument error
|
|
|
|
_make_dirs currently can fail as _DIRS can be really long and thus go over
|
|
the MAX_ARG_STRLEN limit so it will fail with:
|
|
/bin/sh: Argument list too long
|
|
|
|
Lets avoid this by stripping the $(BUILDDIR) prefix and then restoring it.
