[Clfs-dev] GCC command line option cleanup

[William Harrington]

Greetings,

Throughout the various GCC version changes, some configure options  
have been added, some may be obsolete, and some may not change.

We need to verify the GCC builds in cross tools, temp system, and  
final system to make sure we have configure options that are needed,  
aren't needed.

Some options may be auto, as well and may not need to be included with  
the configure line.

We have to be sure for cross-tools GCC that we understand that the  
host system may not be a GNU/Linux host and so some options which  
default based on a linux host do not get used and that we specifically  
set the options for a linux target.

Final system should be the easiest to determine if the configure  
options are good as they are or if some need to be removed, added  
based on what is auto.

Chris mentioned a ticket LFS has for this, as well, but they are  
targeting for GCC 4.9.

All is fine as it is, but we may be able to reduce the command line  
options for configure in each of the GCC builds in the book. Has  
anyone already looked into this?

Perhaps we should create a ticket for this, as well.

Sincerely,

William Harrington
