[ewg] Fedora 14: gcc: cannot specify -o with -c, -S or -E with multiple files

[Jeremy Enos]

Thanks Ken-
This definitely got me further, and was good advice.  Looks like it's 
been an issue for some time w/ Fedora kernel source.
http://www.g-loaded.eu/2005/12/14/the-complete-fedora-kernel-headers/

Unfortunately, there were many more potholes ahead- mostly implicit 
declaration errors that required additional include lines for kernel 
headers.  But then the showstoppers came up... struct device changes, 
function argument mismatches, etc.

I wish the ofa_kernel package development wasn't so anchored by 
enterprise distros.  Making it compatible w/ more recent kernels is work 
that eventually needs to be done anyway- doing it sooner would allow for 
that much more pre-enterprise testing.  (and I wouldn't have to rebuild 
all the applications that I prefer not to be dark age versions in order 
to have a distro that is ofed compatible)  :(
