This patch would seem to prevent Codesourcery toolchains from working.  They
use "arm-none-linux-gnueabi-*" (no $(LIB) part).
I suppose you can't take everyone into account but was just curious to know
if this was taken into account.

The GNU target name is distinct from the toolchain prefix. For external
toolchains, the toolchain prefix is still configurable using the
BR2_TOOLCHAIN_EXTERNAL_PREFIX configuration option.

If you have any issue, could you post the corresponding build log
and .config file ?

Best regards,

The problem occurs at the configure stage of gdb (target):

checking build system type... i686-pc-linux-gnu
checking host system type... Invalid configuration
`arm-unknown-linux-glibcgnueabi': machine `arm-unknown-linux' not recognized

This is passed from the gdb.mk file to ./configure using the
REAL_GNU_TARGET_NAME variable, which gets its value from GNU_TARGET_NAME, as
calculated by the patch I'm highlighting.
Maybe this should be made conditional on not using an external toolchain?

I will provide .config and build output if required but don't think it is
necessary, let me know if I am wrong on this.  (Also is an attachment OK?
 .config is over 14 KiB).

Ok, reproduced. Fix implemented and being tested, should be sent to the
list soon. Thanks for letting us now about the issue!
