Make .note.android.ident section type SH_NOTE The .note.android.ident section is only used by GDB, which doesn't care what section type the section is, but it would be convenient for readelf -n to be able to find the section too. The old way of getting the .note.android.ident section to be of type SH_NOTE involved compiling from .c to .s using gcc, running sed to change progbits to note, and then compiling from .s to .o using gcc. Since crtbrand.c only contains a section containing data, a crtbrand.S can be checked in that will compile on all platforms, avoiding the need for sed. Also add crtbrand.o to crtbegin_so.o so that libraries also get the note, and to the crt workaround in arm libc.so. Change-Id: Ica71942a6af4553b56978ceaa288b3f4c15ebfa2

Remove no-op sed step when compiling crtbrand.o crtbrand.c was compiled to a .s file, run through a sed script to translate a %progbits to %note, and the compiled to .o. However, when the sed command was copied from the original source it was not updated to use the new name of the section (.note.ABI-tag to .note.android.ident), so it didn't modify the file. Since the section has been generated with type %progbits instead of %note for two years, just delete the whole sed step. Change-Id: Id78582e9b43b628afec4eed22a088283132f0742

Reconfig libc's Android.mk to build for multilib 1. Moved arch-specific setup to their own files: - <arch>/<arch>.mk, arch-specific configs. Variables in those config end with the arch name. - removed the extra complexity introduced by function libc-add-cpu-variant-src, which seems to be not very useful these days. 2. Separated out the crt object files generation rules and set up the rules for both TARGET_ARCH and TARGET_2ND_ARCH. 3. Build all the libraries for both TARGET_ARCH and TARGET_2ND_ARCH, with the arch-specific LOCAL_ variables. Bug: 11654773 Change-Id: I9c2d85db0affa49199d182236d2210060a321421
