   4 # configure that affect powerpc64 and powerpc64le.

   6 # The issue causes configure to incorrectly determine that shared library
   7 # support is not present in the linker. This causes the package to build a
   8 # static library rather than a dynamic one and although the build will succeed,
   9 # it may cause packages that link with the static library it to fail due to
  10 # undefined symbols.

  12 # This script searches for files named 'configure' that appear to have this
  13 # issue (by searching for a known bad pattern) and patching them.
