Hmm, it turns out build still fails for me, this time in the link step:
linux-ppc-ipa.o: In function `alloc_jump_pad_buffer':
gdb/gdbserver/linux-ppc-ipa.c:121: undefined reference to `getauxval'
Looking at tracepoint.c, I notice that the definition of getauxval
#if !defined HAVE_GETAUXVAL && defined IN_PROCESS_AGENT
/* Retrieve the value of TYPE from the auxiliary vector. If TYPE is not
found, 0 is returned. This function is provided if glibc is too old. */
unsigned long
getauxval (unsigned long type)
is itself within a
#ifndef IN_PROCESS_AGENT
block, and so never has any effect ...
Bye,
Ulrich
