   3 # Possible flavourisation in DEB_BUILD_OPTIONS (in addition
   4 # to stock Debian rules):
   5 # - static (use with system libc; default for all others)
   6 # - shared (use with klibc or musl)
   7 # - diet, klibc, musl
   8 # - debug (adds -g3)
   9 # - nopwnam (aids static linkage)
  10 # - nofpu (default with klibc)
  11 # - nommu
  12 # - nolibs (use with system libc; default for all others)
  13 # - noautotools (on systems lacking autotools-dev)
  14 # - noselinux
  15 # The 'nostrip' and 'parallel=n' options are supported as well.
  16 #
  17 # Using a non-system libc disables -O0/-O2 and -g and, if unset,
  18 # sets CC. Cross-compiling also sets CC if unset.
  19 #
  20 # Statically linking violates the Policy requirement of having a
  21 # Built-Using header, but since that is only used in local rebuilds
  22 # and not in the Debian archive, it constitutes no Policy violation.
