-dnl The custom linker doesn't support text relocations, but NDK >= r6b
-dnl creates some (http://code.google.com/p/android/issues/detail?id=23203)
-dnl We however want to avoid these text relocations, and this can be done
-dnl by making gcc not link crtbegin and crtend. In the broken NDKs, crtend
-dnl doesn't contain anything at all, beside placeholders for some sections,
-dnl and crtbegin only contains a finalizer function that calls
-dnl __cxa_finalize. The custom linker actually takes care of calling
-dnl __cxa_finalize when the library doesn't call it itself, which makes it
-dnl safe not to link crtbegin. Besides, previous versions of the NDK didn't
-dnl link crtbegin and crtend at all.

-# versions of a given application (e.g. Aurora and Firefox both use
-# "Firefox"), but may vary for full rebrandings (e.g. Iceweasel). Used
-# for application.ini's "Name" field, which controls profile location in

-# integration hooks (Unix remoting, Windows MessageWindow name, etc.)
-# - MOZ_APP_DISPLAYNAME: Used in user-visible fields (DLL properties,

-# builds (e.g. Aurora for Firefox).

-# - MOZ_APP_VERSION_DISPLAY: Defines the application version number. Used
-# in the "About" window. If not set, defaults to MOZ_APP_VERSION.
-# - MOZ_APP_NAME: Used for e.g. the binary program file name. If not set,
-# defaults to a lowercase form of MOZ_APP_BASENAME.
-# - MOZ_APP_REMOTINGNAME: Used for the internal program name, which affects
-# profile name and remoting. If not set, defaults to MOZ_APP_NAME.
-# - MOZ_APP_PROFILE: When set, used for application.ini's
-# "Profile" field, which controls profile location.
-# - MOZ_APP_ID: When set, used for application.ini's "ID" field, and
-# crash reporter server url.
-# - MOZ_APP_ANDROID_VERSION_CODE: On Android, "android:versionCode" for
-# the main application is set to the value of this variable.  If not
-# set, it falls back to a Mozilla-specific value derived from the
-# build ID.
-# - MOZ_ANDROID_SHARED_ID: On Android, "android:sharedUserId" for all Android
