[PATCH [iputils] 2/5] doc: fix parallel build of html/man pages

[Mike Frysinger]

The use of the same tempdir prevents building of these files in parallel.
So build all of them in unique tempdirs so we can do them in parallel.

This defaults CFLAGS to -O3 without clobbering settings people have set

Hey Mike,

I'd like to set CC if is unset, check this patch, if it look sane for 
you :)

unfortunately that won't do anything.  make provides a default CC so that code 
will effectively never get used.

you could just delete the line.  realistically, the default (cc) is going to 
be gcc on any system where this code is built.

alternatively, you can use the pattern:
ifeq ($(origin CC),default)
CC = gcc
endif
