patching libbacktrace.mk to build in yocto environment.
|
|
Changes include:
|
Introduced an output folder which will keep all the outputs from the
|
android-tools.
|
|
Adding an include file that is setting the common flags.
|
Changed the cppflag to include the headers from other components
|
of android-tools
|
|
Modified LDflags so that the libraries that are coming from other android-tools
|
are searched in the output folder.
|
|
Modified the build rule so that it outputs the binary to the OUT_DIR
