[build] Add the flags to enable cross-compiling the corelibs
|
|
|
|
Pass the Swift and CMake flags needed to cross-compile Foundation and so on, with
|
|
the first example of Android AArch64. Add a new flag, --cross-compile-deps-path,
|
|
which is used to search for cross-compiled libraries, like libcurl, that the
|
|
corelibs depend on.
