Gaah, yes, indeed. My suggestion in the bug report was done quickly while at work. --with-liblzma-prefix=$(HOST_DIR)/usr should indeed be passed in HOST_GDB_CONF_OPTS. Thomas

As reported in... https://bugs.busybox.net/show_bug.cgi?id=8786 ..., gdb fails to build with xz and expat support at the same time when using an external toolchain. This is how the problem is shown: checking for liblzma... no configure: error: missing liblzma for --with-lzma And having a deeper look in gdb/config.log we can se a message like this one: /lib64/liblzma.so.5: undefined reference to `clock_gettime@GLIBC_2.17' As Thomas said in the bug report quoted above, that error is related to the fact that it find the host's lzma. Adding --with-lzma-prefix=$(HOST_DIR)/usr to GDB_CONF_OPTS fixes the problem.
