kexec-tools: Pass -r directly to linker
-r is understood by gcc but not by clang, anyway its a linker option so pass it straight to linker by using -Wl explicitly (From OE-Core rev: 3f4ab836d7d9b7a994b65ab8c7ebf6ff65e6277b) Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Ross Burton <ross.burton@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

Subject: [PATCH] purgatory: Pass -r directly to linker
|
||||
|
||||
This helps compiling with clang since -r is not a known option for clang
|
||||
where as gcc knows how to deal with it and passes it down to linker
