Hello,

Git fails to build if LIBS contains -lpthread.  To reproduce:

  export LIBS=-lpthread
  ./configure
  make V=1 git-credential-store

The bug is that linker command line does not contain -lpthread, so
linking fails.

configure respects LIBS and finds that it does not have to add
anything for pthread:

checking for POSIX Threads with ''... yes

But (first bug) configure does not pass the LIBS variable in
config.mak.autogen.  Even if it did, Makefile would overwrite (second
bug) LIBS with:

  LIBS = $(GITLIBS) $(EXTLIBS)

Makefile should rather append to LIBS.
