| """Pack relocations in a library (or copy unchanged). |
| |
| If --enable-packing and --configuration-name=='Release', invoke the |
| relocation_packer tool to pack the .rel.dyn or .rela.dyn section in the given |
| library files. This step is inserted after the libraries are stripped. |
| |
| If --enable-packing is zero, the script copies files verbatim, with no |
| attempt to pack relocations. |
| |
| Any library listed in --exclude-packing-list is also copied verbatim, |
| irrespective of any --enable-packing setting. Typically this would be |
| 'libchromium_android_linker.so'. |
