[PATCH] [ELF] Implement parsing `-l` prefixed items in the `GROUP` linker script command

[Simon Atanasyan]

Hi Bigcheese, shankarke, ruiu,

Implement parsing `-l` prefixed items in the `GROUP` linker script command. There are two forms of `-l` prefixed expression:

* -l<libname>
* -l:<filename>

In the first case a linker should construct a full library name `lib + libname + .[so|a]` and search this library as usual. In the second case a linker should use the `<filename>` as is and search this file through library search directories.
