181989f6c9427fc266dbdcc84cb60ac03e67cdb2 build: Add variable printing target to Makefiles (Carl Dong) Pull request description: ``` I kept finding myself needing these to debug our build system, since they are innocuous and are very helpful they probably belong in the codebase. Source: John Graham-Cumming https://www.cmcrossroads.com/article/printing-value-makefile-variable ``` ACKs for top commit: MarcoFalke: ACK 181989f6c9427fc266dbdcc84cb60ac03e67cdb2 fanquake: ACK 181989f6c9427fc266dbdcc84cb60ac03e67cdb2 - concise amount of useful code. Tested on macOS. Did not visit the link. Tree-SHA512: 2139621e68a499c7347663ca9dc04e166ea6280e05986c27858df0156016ef2f9461262464d70c601419384f43a4ae3bcc67dfc0a05dbeef64f08386ab429cd8
