7e5b0a5978 [ELF] - Don't segfault when accessing location counter inside MEMORY command. 
We would previously crash on next script:
MEMORY { name : ORIGIN = .; }

Patch fixes that.

5fb17128f7 [ELF] - Do not segfault if linkerscript tries to access Target too early. 
Following possible scripts triggered accessing to Target when it was not yet
initialized (was nullptr).

MEMORY { name : ORIGIN = DATA_SEGMENT_RELRO_END; }
MEMORY { name : ORIGIN = CONSTANT(COMMONPAGESIZE); }

Patch errors out instead.
