This option enables or disables the linker addition of:
an extra empty program header table entry to an application
some extra DT_NULL dynamic tags to both applications and shared libraries.
The prelink tool uses this reserved space to write extra information that is needed by the dynamic loader.
The --prelink_support option only has an
effect when the --sysv option is selected. Building for
ARM Linux with the --arm_linux command line option
turns on several command line options that make the linker behave
like GNU ld, and includes --sysv.
Use --no_prelink_support to force the linker
not to reserve the extra space when building for ARM Linux.
