linux/armv7l: No valid platforms to build for on Raspberry Pi 2B V1.1
On Raspberry Pi 2B V1.1 compiling gitlab-runner fails:
make[1]: mage: No such file or directory
No valid platforms to build for. If you specified a value
for the 'os', 'arch', or 'osarch' flags, make sure you're
using a valid value.
A simple fix to get the compile going for me is replacing 'armv7l' with 'arm', similar to 'aarch64' becoming 'arm64':
sed -i 's#s/aarch64/arm64/#s/aarch64/arm64/ ; s/armv7l/arm/#g' Makefile.build.mk
