[uml-devel] [PATCH] um: v2: Fix gcc-plugins dependency

[Thomas Meyer <thomas@m3y3r.de>]

Ensure to build the gcc-plugins for user-offsets.s

The target arch/x86/um/user-offsets.s is build with normal CC flags, i.e with
gcc plugins, e.g. -fplugin=./scripts/gcc-plugins/latent_entropy_plugin.so

Ensure to build all gcc-plugins before trying to build this target; else an error
message is thrown:

cc1: error: cannot load plugin ./scripts/gcc-plugins/structleak_plugin.so
   ./scripts/gcc-plugins/structleak_plugin.so: cannot open shared object file: No such file or directory
cc1: error: cannot load plugin ./scripts/gcc-plugins/latent_entropy_plugin.so
   ./scripts/gcc-plugins/latent_entropy_plugin.so: cannot open shared object file: No such file or directory
cc1: error: cannot load plugin ./scripts/gcc-plugins/randomize_layout_plugin.so
   ./scripts/gcc-plugins/randomize_layout_plugin.so: cannot open shared object file: No such file or directory
