# The GCC binaries (gcc, g++, etc) can have their name prefixed
# by specifying a program-prefix option when configuring.
# https://gcc.gnu.org/install/configure.html
#   Search above page for "--program-prefix"
# The prefix allows multiple GCC to be installed and on system PATH.
# MINGW (Which we use for crosscompilation) uses this option.
#   x86_64-w64-mingw32- and i686-w64-mingw32-
# GCC as built by Linux distros usually uses this option.
#   however the prefixes vary

# Default prefix to "x86_64-linux-gnu-", but allow overriding.
#   (For example Fedora 25 is noted needing something like "x86_64-redhat-linux-")
# NOTE: ${x-y} is a bash-ism. differs from portable ${x:-y} if x undefined
