Hi,

This is a follow up from
lkml.kernel.org/r/<20180329004805.7278-1-labbott@redhat.com> . I was
pointed to a previous suggestion (https://lkml.org/lkml/2018/2/28/178)
to rename the variables for better namespacing. I hadn't seen anyone
follow up so this is a series to do just that. I split up the rename by
variable for ease of review. This was mostly just a pretty
straight-forward search and replace. I intentionally didn't Cc all the
outside maintainers on the rename because I wanted to make sure this
approach was correct before bothering people.

This series also includes two other issuse I found to finally have all
the generated files pick up the host flags. The first seems to be a typo
of CHOSTFLAGS instead of HOSTCFLAGS. The second is a missing HOSTLDFLAGS
when linking fixdep. I put these two separately in case there was
interest in picking them up for stable.

For the interested, the full command line I've been testing with:

HOSTCFLAGS="-O2 -g -pipe -Wall -Werror=format-security
-Wp,-D_FORTIFY_SOURCE=2 -Wp,-D_GLIBCXX_ASSERTIONS -fexceptions
-fstack-protector-strong -grecord-gcc-switches
-specs=/usr/lib/rpm/redhat/redhat-hardened-cc1
-specs=/usr/lib/rpm/redhat/redhat-annobin-cc1 -m64 -mtune=generic
-fasynchronous-unwind-tables -fstack-clash-protection -fcf-protection"

HOSTLDFLAGS="-Wl,-z,relro -Wl,-z,now
-specs=/usr/lib/rpm/redhat/redhat-hardened-ld"

Thanks,
Laura
