BUILD: Makefile: add a "make opts" target to simply show the build options
|
|
|
|
We're often missing an easy way to map input variables to output ones.
|
|
The "opts" build target will simply show the input variables and the ones
|
|
passed to the compiler and linker. This way it's easier to quickly see
|
|
what a given build script or package will use, or the detected warnings
|
|
supported by the compiler.
|
|
|
|
(cherry picked from commit a8b12c6bb73b924f6429c3ae4d20b96992e92c2e)
|
|
[wt: this is not needed but significantly helps for packaging]
