# Choosing the correct pkgdesc
#--------------------------------------------------------------------------------
# You must know wether your toolchain is a bare-metal one, if it's specifically for big-endian or
# little-endian order and know its full name, if possible. Here are some useful tips:
#
# * If the toolchain has no operating system (see the toolchain triplet, <_os_target>), then it's a
# bare-metal toolchain, in which case you have to specify it in the pkgdesc
#
# * Do a bit of research in forums, wikis and documents about the target you plan to build, a good
# idea is to see the description that other distros put (e.g. Debian) if they have the same toolchain
#
# Example: arm-linux-gnueabi-{gcc,binutils,$etc}
# This toolchain has GNU/Linux as OS, so it's not a bare-metal one. It's for armel, which
# stands for "ARM EABI little-endian", but the gnueabi part means it uses the GNU EABI. You can find
# that info in Debian's gcc-arm-linux-gnueabi and a couple of FLOSS and programmers community forums.
# Toolchain triplet: <_arch>-<machine>-<_os_target>
# <machine> is generally optional and uneeded
_target=x86_64-pc-linux-gnu
# This are some options for names. Change $_target_name in pkgdesc according to the target architecture
