Script to assemble, link, execute, and debug ARM assembly

Usage: ./arm_compile.sh [-h|-e|-l|-g|-o <file>] -f <targetfile>
h    Print this help
e    Execute after linking
l    Link C library when compiling
g    Debug with gdb (You will need to open another terminal to run gdb)
o    Specify output file (default: same as target)
f    Specify target file

Script will leave assembled .o files as well as ARM binary, all with the same name as targetfile (NOT a.out) unless -o specified.
