makefiles/tools: Automatically detect gdb-multiarch Modern versions of GDB support multiple targets with the same gdb binary. At least Ubuntu and Debian have dropped the gdb-arm-none-eabi package in favour of gdb-multiarch. Here, no $(PREFIX)-gdb binary is availiable, instead gdb-multiarch should be used. This patch tries to automatically detect the presense of gdb-multiarch and uses it instead of arm-none-eabi-gdb. 2019-03-05 14:31:22 +01:00			`# new versions of gdb will support all architectures in one binary`
makefiles: Sort >/dev/null and 2>&1 Redirecting `2>&1 >/dev/null` moves stderr to stdout first and then stdout to /dev/null; when checking for command existence or otherwise silencing output, this is usually not desired (but only starts producing errors when the actual command fails, which is often not tested). 2021-08-24 14:39:04 +02:00			`ifeq ($(shell gdb-multiarch -v > /dev/null 2>&1; echo $$?),0)`
