Apple M1 ARM GDB Build from Source with Python Support

build_gdb.sh

#!/usr/bin/env sh

# NOTE: First, have to ignore the following warnings to make it build on M1 Chip.
#
#       -Wno-constant-logical-operand -Wno-format-nonliteral -Wno-self-assign
#
#       To do so the above line should be appended to consts CFLAGS and CXXFLAGS
#       under the 'Programs producing files for the HOST machine' section of 
#       the generated Makefile in dir 'build-gdb'.
#       With the new updated flags clang should be able build gdb successfully with
#       no more errors. Rerun "make" and then "make install" while in the "gdb-build"
#       dir. 
#       
#       Second, be sure to update 'with-python' and 'with-libgmp' flags below to appropriate
#       location on personal system so gdb knows where to find them.
#       
#       Third, copy line 24 and 25 to terminal rc file i.e. .zshrc|.bashrc|etc ... so gdb is 
#       on terminal PATH.
#       
#       Fourth, enjoy debugging on the M1 with GDB.

Hey guys, I apologize for late response! This script that I posted only works for arm-none-eabi. I haven't personally tried to compile gdb for aarch64 since its not supported. Essentially, it's an abi issue. Check out gcc-darwin-arm64 for further support (haven't tried it yet). Thanks @JayFoxRox for the link!
