llvm dev - May 2017 - Missing symbol __executable_start on Android when linking with LLD

When linking a project with lld, the android libc links to
__executable_start
which isn't defined when linking with lld (tried on x86), but is when
linking with gnu ld it seems. 

I tried:

.globl	__executable_start
__executable_start = __ehdr_start

as a workaround but seems to be ignored.

Anyone know a better workaround?

Thanks,

It is missing from lld.

Do you know what it should point to? The first executable PT_LOAD?

Thanks,
Rafael

Android libc casts its address to the elf header type. So I think start of text?
