# Provide CI which utilize buildroot and the test-pkg utility to build c-periphery
# against the following toolchains:
#   - br-arm-full
#       ARM toolchain with uClibc
#   - br-arm-cortex-a9-glibc
#       ARM toolchain with glibc and a very recent gcc version
#   - br-arm-cortex-m4-full.
#       ARM noMMU toolchain with no dynamic library support
#   - br-x86-64-musl
#       x86-64 musl toolchain
#   - br-arm-full-static
#       ARM toolchain which is fully static (doesn't support dynamic libraries)
#   - sourcery-arm
#       ARM toolchain with an old gcc version (gcc 4.8)
#
# Build logs are upload as part of the last step
