Subject: [PATCH] kernel.bbclass: unset LDFLAGS when run devshell in kernel
 recipe

When user runs devshell in kernel recipe and compiles kernel,
this will fail by unrecognized option of LD.

----
$ make
...
arm-poky-linux-gnueabi-ld: unrecognized option '-Wl,-O1'
arm-poky-linux-gnueabi-ld: use the --help option for usage information
----

This set to empty LDFLAGS when user runs the devshell, and solve this problem.
