For the runtime overhead issue, I feel my suggestion to FFMPEG community still
helps though there might be extra symbols added in the symtab.
Reading the thread, I saw Martin said it doesn't work for assembler for some
other platforms but I guess for linux + gas it should always work.
i.e something like the following for arm kernel code:
...
.ifdef \sym\()_lazy
.eqv \sym\()_lazy, \sym
.endif
adr\c \rd, \sym\()_lazy + 1
...
