xfsprogs: CFLAGS not passed in

I saw Christian Kujau's report yesterday with a quick fix, so maybe my 
reports of a similar problem have been missed in the thread "rsync and 
corrupt inodes (was xfs_dump problem)" and this is a repost:

I tried to compile xfsprogs with the "CFLAGS":
CFLAGS="-march=athlon64-sse3 -g -Os" ./configure --prefix=/usr

No matter what I use for CFLAGS, the resulting binary repair/xfs_repair 
is always the same. So it seems to be ignored during compile anyway. 
Smells like a bug? Because config.status gets the CFLAGS set, it's just 
not used during compile. Comparing a "config.status" with CFLAGS set and 
without:

# diff config.status config.status.default
360c360                                                                 
<   with options \"'--prefix=/usr' 'CFLAGS=-march=athlon64-sse3 -g -
Os'\"
---
>   with options \"\"

<   set X '/bin/sh' './configure'  '--prefix=/usr' 'CFLAGS=-
march=athlon64-sse3 -g -Os' $ac_configure_extra_args --no-create --no-
recursion
---
>   set X '/bin/sh' './configure'  $ac_configure_extra_args --no-create 
--no-recursion

< S["CFLAGS"]="-march=athlon64-sse3 -g -Os"
---
> S["CFLAGS"]="-g -O2"


I even set all variables with "GCC" in config.status to random 
content, and it compiles. Then I found that the one in 
"include/builddefs" gets always set to this:
GCCFLAGS = -funsigned-char -fno-strict-aliasing -Wall

So I changed it manually:
GCCFLAGS = -march=athlon64-sse3 -g -Os -funsigned-char -fno-strict-
aliasing -Wall
and now the resulting binary is different. I guess that should not be 
happening? I'm used to setting "CFLAGS=" during configure to have 
smaller bins, and CFLAGS normally get passed through during compile, but 
not with xfsprogs. Maybe worth a fix?
