[committed/darwin]: Set section size of dsymfile bfd

[Tristan Gingold]

Hi,

contrary to ELF .gnu_debuglink files, the section size of dsymfile are set to 0 (because there is no
notion of filesize vs memsize in a section).  As a consequence no obj_section was created for these sections
and there was no offset for them.  But offsets are required for shared libraries.

This patch simply copy section size from the bfd to the dsym bfd.

Tristan.

	* machoread.c (macho_symfile_read): Set section size of dsym bfd
	from main bfd.
