Subject: [PATCH] [ARC] Add multilib support for linux targets
|
|
|
|
|
|
|
|
|
|
We used to build baremetal (AKA Elf32) multilibbed toolchains for years
|
|
|
|
|
now but never made that for Linux targets since there were problems with
|
|
|
|
|
uClibc n multilib setup. Now with help of Crosstool-NG it is finally
|
|
|
|
|
possible to create uClibc-based multilibbed toolchains and so we add
|
|
|
|
|
relevant CPUs for multilib in case of configuration for "arc*-*-linux*".
|
|
|
|
|
|
|
|
|
|
This will be essentially useful for glibc-based multilibbbed toolchains
|
|
|
|
|
in the future.
