Bugzilla Bug 75538

Due to a *bad* CFLAGS configuration (double space between words). emerge failed
without a signifficant error that let the user fix it easily (two months that
it is in my box :-)).

This issue has been already raised in 3 bug reports. I think to remove noise,
we should provide a fix or a warning.

What is very funny, it is the only ebuild which fails !!!

Please note that two other bugs exist (at least) on this topic, they are closed
BUT the but is in the field. #46554 and #58263

Reproducible: Always
Steps to Reproduce:
1. Add a space in your CFLAGS as in CFLAGS="-march=athlon-tbird  -O3 -pipe
2. emerge cyrus-sasl
3.

Expected Results:  
ebuild was emerged gracefully :)

Same bug to see:  38601

I've just tried emerging both cyrus-sasl-2.1.20 and cyrus-sasl-2.1.20-r1 with
following CFLAGS and it worked with every one:

CFLAGS=" -march=pentium4 -O2 -pipe -fomit-frame-pointer"
CFLAGS="-march=pentium4  -O2 -pipe -fomit-frame-pointer"
CFLAGS="-march=pentium4 -O2 -pipe  -fomit-frame-pointer"
CFLAGS="-march=pentium4 -O2 -pipe -fomit-frame-pointer "

Sorry for the report not full, I expect this one is better.

My exact CFLAGS is 
CFLAGS="-march=athlon-tbird -O3 -pipe -m3dnow -mmmx -fomit-frame-pointer -ffast-math -funroll-loops -fforce-addr -falign-functions=4"

The one which does not work is 
CFLAGS="-march=athlon-tbird -O3 -pipe -m3dnow -mmmx -fomit-frame-pointer -ffast-math  -funroll-loops -fforce-addr -falign-functions=4"

Just tested now and it failed :-(

Still the same error:
