Looks like this could be fixed by " [binutils-gdb] Fix build with latest GCC
9.0 tree" ( https://sourceware.org/ml/gdb-cvs/2018-12/msg00038.html ):

Fix build with latest GCC 9.0 tree
A recent patch [1] to fix a GCC PR [2] actually broke the GDB build.
To fix, remove the stack pointer clobber. GCC will ignore the clobber
marker, and will not save or restore the stack pointer.
I ran "make check-gdb" on x86_64 to ensure there are no regressions.
gdb/ChangeLog:

* nat/linux-ptrace.c (linux_ptrace_test_ret_to_nx): Remove sp clobbers.
