ASan unittest (32-bit) fail to link with fresh googletest

[GoogleCodeExporter]

What steps will reproduce the problem?
1. rm -rf third_party/googletest
2. svn co http://googletest.googlecode.com/svn/trunk -r608 
third_party/googletest
3. <rebuild ASan>
4. make -f Makefile.old t32

What is the expected output? What do you see instead?
Linker produces error:

I'm also seeing a problem with one of my program (but by compiling it 
statically)

unresolvable R_386_PC32 relocation against symbol `.......`

I've seen it for strcpy, strchar, ... and I don't know why it's happening, what 
could be the source of this problem ?

(GCC compile the same code just fine)

Does this happens with -faddress-sanitizer?
Could you please send exact linker error messages?


I guess the problem in this issue is that we define our own "sigaction"
with slightly different signature, which confuses ld.
I'm testing a fix for this.

Yes using Asan it got fixed in my case by reordering my different LDFLAGS i.e. 
putting -lpthread more toward the end and so on.

r149247 should fix this. Our replacements/wrappers for functions like sigaction 
or strcpy didn't have default visibility.
