Make musl provide libssp_nonshared.a and make GCC link it unconditionally if musl is used. This should be a no-op if SSP is disabled and seems to be the only reliable way of dealing with SSP over all packages due to the mess that is linkerflags handling in packages.

This adds a -jX option to certain packages that are known to behave well

to the make command.

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.

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.
