6839382480 asmtest: avoid testing against complex nop alignment in gas 
.align #,0x90 in gas ignores the 0x90 and outputs any kind
of nop it feels like.  the one avoided by this patch is a 7
byte nop, which gas has been doing since at least 1999:
http://sourceware.org/ml/binutils/1999-10/msg00083.html

In order to match what gas does, we would need to make
code alignment target-specific, import a lot of code, and
face the question: exactly which gas {version,target,tune}
combo are we trying to match?  see i386_align_code in:
http://sourceware.org/cgi-bin/cvsweb.cgi/src/gas/config/tc-i386.c?annotate=1.460&cvsroot=src

The smart noppery is turned on via the special casing of 0x90
at line 438 in md_do_align in:
http://sourceware.org/cgi-bin/cvsweb.cgi/src/gas/config/tc-i386.h?annotate=1.1&cvsroot=src

0a50e6c933 tcc.c: fix an error when you build an object file with '-pthread' key set 
The problem was partially fixed by Henry in the following patch:

    tcc.c: skip -lpthread when -c option specified

But that patch had one brawback: it is sensitive to argument order,
as decision is taken during commandline parsing:

    $ tcc -c a.c -o a.o -pthread # 1. works fine
    tcc: error: file 'a.c' not found

    $ tcc -pthread -c a.c -o a.o # 2. blows
    tcc: error: cannot specify libraries with -c

This patch fixes case 2.

0ae39f1957 Handle r_addend and R_X86_64_PLT32 properly. 
- r_addend should be applied for PLT entries as well
- R_X86_64_PLT32 should be handled just like R_X86_64_PC32
- spec says GLOB_DAT and JUMP_SLOT don't need r_addend (not tested)
  http://www.x86-64.org/documentation/abi.pdf

Now we can -run ELF objects generated by GCC.

f2d7998a96 Copy tcclib.h to tests directory so GCC uses its own headers. 
86ffc48129

removed this cp command. However, it was necessary to pass tests on x86-64
because include/stdarg.h is different from GCC's definition on x86-64.
