* build-aux/ndk-build-helper-1.mk: * build-aux/ndk-build-helper-2.mk: * build-aux/ndk-build-helper.mk: Do not generate file names with redundant directory separators, to port to systems where the semantics of this are undefined. * configure.ac: Provide a cache file to the recursive invocation of configure if one is specified for the initial. * cross/ndk-build/Makefile.in (my-dir): Better conform to the original ndk-build by generating directory names with no trailing separator. * m4/ndk-build.m4 (ndk_resolve_import_module, ndk_SEARCH_MODULE): Cache the names of Android.mk files and the commands produced from them.
This directory holds Makefiles and other required assets to build an Emacs binary independently for another toolchain. The directory ndk-build also contains an implementation of the Android `ndk-build' build system.
