Hi Michelle,
This error can be easily resolved.
The meta-linux layer depends on the poky layer. The poky layer contains the main gdb-cross_x.x.bb recipe. A corresponding gdb-cross_x.x*.bbappend in the meta-xilinx layer will append to the recipes in the poky layer.
In this case, your poky and meta-xilinx branches may not be matched, and the gdb-cross_7.7.bb recipe might have been updated to a newer version, hence the .bbappend from the meta-xilinx layer fails for that particular recipe version.
A quick way to resolve this error is to either:
01. Check out the correct branch for both the poky and meta-xilinx layers.
The daisy branch is the latest (1.6), the dora branch is the previous release (1.5).
git checkout -b daisy --track remotes/origin/daisy
or
git checkout -b dora --track remotes/origin/dora
for both the poky and meta-xilinx layers, and then try to do a
$ bitbake core-image-minimal
This will build the toolchain, kernel and root filesystem.
02. Delete the offending *.bbappend from the meta-xilinx layer.
Review what the .bbappends are doing, though, since it might be adding support for microblaze to gdb, etc.
You should subscribe to the meta-xilinx mailing list, since most of the people from Xilinx who maintain the meta-xilinx layer actively participate on the mailing list.

Let me know how it goes.
