Subject: [PATCH] btrfs-progs: build: fix building libbtrfs.so with tsan

Except libbtrfs.so object, all other tools compile fine. The error is:

ld: send-stream.o: relocation R_X86_64_PC32 against symbol
`stderr@@GLIBC_2.2.5' can not be used when making a shared object;
recompile with -fPIC

Compiling with -fPIC fixes the problem.
