Enables IPv6 support in kernel (builtin) and packages.
config PKG_BUILD_PARALLEL
bool
prompt "Compile certain packages parallelized"
default y
help
This adds a -jX option to certain packages that are known to behave well
for parallel build. By default, the package make processes use the main
jobserver, in which case this option only takes effect when you add -jX
to the make command.
If you are unsure, select N.
config PKG_BUILD_USE_JOBSERVER
bool
prompt "Use top-level make jobserver for packages"
depends on PKG_BUILD_PARALLEL
default y
help
This passes the main make process jobserver fds to package builds,
enabling full parallelization across different packages.
Note that disabling this may overcommit CPU resources depending on the
-j level of the main make process, the number of package submake jobs
selected below and the number of actual CPUs present.
Example: If the main make is passed a -j4 and the submake -j
is also set to 4, we may end up with 16 parallel make processes
in the worst case.

help
Always set the default package build rules to parallel build.
WARNING: This may break build or kill your cat, as it builds packages
with multiple jobs that are probably not tested in a parallel build
environment.
Only say Y if you don't mind fixing broken packages. Before reporting
build bugs, set this to N and re-run the build.
