typos.
- Do not use HOST_EXTRA*FLAGS. Add new user specifiable variables.
- Pass HOSTLDFLAGS to build single .c programs.
- Build objtool with host flags.
Robin Jarry (3):
kbuild: introduce HOST_{C,LD}FLAGS
kbuild: use HOSTLDFLAGS for single .c executables
objtool: use global host flags
Add user-specifiable compiler/linker flags for host programs. Append
these to already existing HOST{C,CXX,LD}FLAGS.
Update documentation accordingly.

When compiling executables from a single .c file, the linker is also
invoked. Pass the HOSTLDFLAGS like for other linker commands.

Hi Josh,
Shame on me... Last minute fix. I had tested this first by forcing
HOSTCC="gcc " but I found it rather

Add a new user specifiable variable to provide specific linker options
(-L, -rpath, ...) for host programs build.
Append these options to HOSTLDFLAGS.
