Uefi hello example with pre-built libraires to link

Uefi standard (http://www.uefi.org/) firmware
(https://github.com/tianocore/edk2) can build with ld, but cannot build with
gold linker. When link a uefi module, the gold will report internal error in
do_layout as blew.

ld-new: internal error in do_layout, at ../../binutils-2.26/gold/object.cc:1819

Attachment is a Uefi hello example with pre-built libraires, you can direclty
extract it and link them with ld and ld-new:

gold 2.26 will fail as below:
"ld-new" -o Hello.dll -nostdlib -n -q --gc-sections -z common-page-size=0x40
--entry _ModuleEntryPoint -u _ModuleEntryPoint -Map Hello.map -melf_x86_64
--oformat=elf64-x86-64 --start-group  @static_library_files.lst --end-group
--defsym=PECOFF_HEADER_SIZE=0x228 --script=GccBase.lds
ld-new: internal error in do_layout, at ../../binutils-2.26/gold/object.cc:1819


but ld 2.26 will succeed:
"ld" -o Hello.dll -nostdlib -n -q --gc-sections -z common-page-size=0x40
--entry _ModuleEntryPoint -u _ModuleEntryPoint -Map Hello.map -melf_x86_64
--oformat=elf64-x86-64 --start-group  @static_library_files.lst --end-group
--defsym=PECOFF_HEADER_SIZE=0x228 --script=GccBase.lds

BTW, this folder example libraries are abstracted from Uefi Hello module build
as below. If you need, you can build them by yourself
1. Setup EDK2 build environment as steps in the link:
https://github.com/tianocore/tianocore.github.io/wiki/Using-EDK-II-with-Native-GCC
 
2. git clone https://github.com/tianocore/edk2 (e.g. ~/edk2)
3. cd ~/edk2
4. make -C BaseTools
5. source edksetup.sh
6. build -t GCC49 -a X64 -p AppPkg/AppPkg.dsc -m
AppPkg/Applications/Hello/Hello.inf

After build, you can find all intermediate files in below folder
~/edk2/Build/AppPkg/DEBUG_GCC49/X64/AppPkg/Applications/Hello/Hello
