[PATCH v1 0/3] objtool build improvements

[Ian Rogers]

Install libsubcmd and then get headers from there, this avoids
inadvertent dependencies on things in tools/lib. Fix V=1
support. Clean up how HOSTCC is used to override CC to avoid CFLAGS
being set for say gcc, and then CC being overridden to clang. Support
HOSTCFLAGS as a make option.

Ian Rogers (3):
  objtool: Install libsubcmd in build
  objtool: Properly support make V=1
  objtool: Alter how HOSTCC is forced
