Commit 0c3b7e42616f ("tools build: Add support for host programs format")

variable is HOSTCFLAGS. Fix this up.

In preparation for enabling command line CFLAGS, re-name HOSTCFLAGS to
KBUILD_HOSTCFLAGS as the internal use only flags. This should not have any
visible effects.

When compiling host programs, it is possible to set specific flags.
The programs will always be compiled utilising $(HOSTCC) passed

To set flags that will take effect for all host programs created
in that Makefile, use the variable HOST_EXTRACFLAGS.
I will fold this.

Strictly speaking, $(CC) or $(CXX) is used
when linking host programs.
See this.
https://github.com/torvalds/linux/blob/v4.17/scripts/Makefile.host#L95
https://github.com/torvalds/linux/blob/v4.17/scripts/Makefile.host#L112
In fact, there is no definition of 'HOSTLD' in the top Makefile.
I will reword it to:
HOSTLDFLAGS
--------------------------------------------------
Additional flags to be passed when linking host programs.
I will also move this hunk up
after LDFLAGS_MODULE.

I checked this series.
I left minor comments for 3/7 and 7/7.
Unless you disagree,
I will fix them up locally
and queue it to my tree.
Thanks.
