This patch changes the way extensions are built to allow for debugging information to be collected. Debug flags are now used when compiling and linking the extension source code, generating a debuggable ELF file. The final .llext file is then stripped of unneeded symbols, including all debugging information, at packaging time. The debugging flag is still removed from the EDK-exported flags.
