[Buildroot] 'make ARCH=arm' warning, how can I correct?

[Buildroot] 'make ARCH=arm' warning, how can I correct?

[Tony Mozi]

Hello all,
I make the cross-compilation for an ARM.

When I make 'make ARCH=arm', I have some errors :

<stdin>:91:1: warning: "__IGNORE_sync_file_range" redefined
In file included from <stdin>:2:
include/arm/unistd.h:444:1: warning: this is the location of the previous definition
<stdin>:1097:2: warning: #warning syscall fadvise64 not implemented
<stdin>:1265:2: warning: #warning syscall migrate_pages not implemented
<stdin>:1321:2: warning: #warning syscall pselect6 not implemented
<stdin>:1325:2: warning: #warning syscall ppoll not implemented
<stdin>:1365:2: warning: #warning syscall epoll_pwait not implemented

How can I correct?

Do not use 'make ARCH=arm' with Buildroot. Use 'make menuconfig' and select
the target architecture in the menu. See 'make help' for some predefined
configurations.

Hi,
Thank you for your answer Bj?rn Forsman.

I have already make 'make menuconig', I modified
        Target Architecture (arm) --->
        Target Architecture Variant (arm922t) --->
        Target ABI (0ABI) --->
Then I make a 'make'.

I added the PATH with the correct link and export CROSS_COMPILE="arm-linux-uclibc-"
Well, I supposed that I can make 'make ARCH=arm'.
But I have these warnings and I don't know if they are important or not.

When I start the SDK, I have 'Welcome to Buildroot buildroot login:' I have not this pass. 
I want to remove it, but I don't know where?

Simply modify the file /etc/issue to your taste.
This text file holds the greeting.
I wouldn't worry too much about the compile warnings, they are normal.
