Issue building gdb on Apple silicon

[Shan Huang]

Hello,

I have encoutered the issue with building gdb on an Apple m1 machine. Currently these (ar nm objcopy objdump ranlib readelf strip) have been built by using ./configure --target=arm64-apple-darwin21.4.0 However, inside gdb subfolder I found there is no gdb executable being created. I tried to using the ./configure inside gdb subfolder, I have encoutered with the gmp missing, after I install it and supplied with --with-libgmp-prefix= PATH/TO/GMP, another error shows "../gnulib/Makefile.gnulib.inc: No such file or directory". I have checked https://sourceware.org/pipermail/gdb-patches/2020-October/172571.html However seems it's not the same. I wonder is there a way I could install gdb on M1 at the moment? Thanks very much.

Best,
Shan

 From what I can see, GDB doesn't support Darwin on aarch64, although other tools in binutils/ do.

The supporting code needs to be contributed to GDB to make that work correctly, like it does for x86_64.
