Alexei Frolov	4c0428a0d8	Define Linux clang target as toolchain ... This change configures the Linux clang -Og target as a toolchain with args. To support this, all Pigweed variables from pw_vars_default are made into build args, defined within their respective modules. The Linux clang target/toolchain is the only one that currently works. Pigweed's other targets will be ported in later changes. Change-Id: I051e29fde7577e41a3184c37031a4e04936404e1	2020-06-16 09:50:59 -07:00
