If you define some symbols in different object files as being placed in a
section with the same name (with __attribute__((section))), ld does not collect
these objects together correctly if the --section-start option is used.
Instead, one of the shards from the first file on command line is placed at the
correct address, and the rest shards of the same section are appended to either
.text or .data sections.
A simple example is attached. There are two object files a.o and b.o, every one
contains a variable with __attribute__((section(".zzz"))). If they are linked
together with option -Wl,--section-start=.zzz=0x800000, variable a is placed at
the correct address 0x800000, but variable b is placed at the wrong address
0x6008b4 (in the .data section).
