  77. This adds a -jX option to certain packages that are known to behave well
  78. for parallel build. By default, the package make processes use the main
  79. jobserver, in which case this option only takes effect when you add -jX
  80. to the make command.

  88. This passes the main make process jobserver fds to package builds,
  89. enabling full parallelization across different packages.
  90. Note that disabling this may overcommit CPU resources depending on the
  91. -j level of the main make process, the number of package submake jobs
  92. selected below and the number of actual CPUs present.
  93. Example: If the main make is passed a -j4 and the submake -j
  94. is also set to 4, we may end up with 16 parallel make processes
  95. in the worst case.

  114. environment.

  151. Reduces kernel size by stripping unused kernel exports from the kernel
