common/build-style: add void-cross
common/build-style: add void-cross
this introduces a new build-style void-cross, which can be used to write system crosstoolchain templates; this is to reduce the amount of maintenance, resolve existing problems with the cross toolchain templates and remove repeated codemaster

# This helper is for void system crosstoolchain templates. |
|||
# |
|||
# Mandatory variables: |
|||
# |
|||
# - cross_triplet - the target triplet (e.g. aarch64-linux-gnu) |
|||
# - cross_linux_arch - the source ARCH of the kernel (e.g. arm64) |
|||
# - cross_libucontext_arch - only on musl without cross_gcc_skip_go |
|||
# |
|||
# Optional variables: |
|||
# |
|||
# - cross_gcc_skip_go - do not build gccgo support |
|||
# - cross_binutils_configure_args |
|||
# - cross_gcc_bootstrap_configure_args |
|||
# - cross_gcc_configure_args |
|||
# - cross_glibc_cflags |
|||
# - cross_glibc_ldflags |
|||
# - cross_glibc_configure_args |
|||
# - cross_musl_cflags |
|||
# - cross_musl_ldflags |
|||
# - cross_musl_configure_args |
|||
# |
|||
# configure_args is passed to both bootstrap gcc and final gcc |
|||
# if you need to pass some to one and not the other, use the |
|||
# respective cross_ variables for final gcc and bootstrap gcc |
|||
