[OpenWrt-Devel] [PATCH] scripts: remote-gdb: fix detection with multiple targets

[Karl Palsson]

From: Karl Palsson <karlp at remake.is>

This script always worked when I had a single target, but has been
failing now that I have both "atheros" and "ar71xx" targets.

This change is clearly not perfect, but I can't work out the regexps any
better.

Before:
$ ./scripts/remote-gdb 192.168.255.31:3333
/home/karlp/src/smartgate_firmware/openwrt-bb/build_dir/target-mips_34kc_uClibc-0.9.33.2/libcp210xmanufacturing-1-HEAD/contrib/bin/cp2104-rs485 
Using target mips_34kc (uClibc-0.9.33.2/libcp210xmanufacturing-1-HEAD)
No gdb found! Make sure that CONFIG_GDB is set!

After:
$ ./scripts/remote-gdb 192.168.255.31:3333
/home/karlp/src/smartgate_firmware/openwrt-bb/build_dir/target-mips_34kc_uClibc-0.9.33.2/libcp210xmanufacturing-1-HEAD/contrib/bin/cp2104-rs485 
Using target arch: mips_34kc, libc: uClibc
Attempting to set sysroot:
/home/karlp/src/smartgate_firmware/openwrt-bb/scripts/../staging_dir/target-mips_34kc_uClibc-0.9.33.2/root-ar71xx/
[ gdb starts here normally (but see next patch) ]
