Makefile broken on OSX - linker ld options

[tseemann]

Erik, another minor fix to help vcflib compile on OSX:

  * linking smithwaterman
ld: warning: option -s is obsolete and being ignored
ld: internal error: atom not found in symbolIndex(__ZNKSt3__16vectorINS_4pairIicEENS_9allocatorIS2_EEE8max_sizeEv) for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [smithwaterman] Error 1

This is the error command:

c++ -Wl,-s -Wall -O3 -o smithwaterman smithwaterman.o BandedSmithWaterman.o SmithWatermanGotoh.o Repeats.o LeftAlign.o IndelAllele.o disorder.o

It works if you remove the ",-s" in the LDFLAGS which I think in Linux/GCC just strips the symbol table.

LDFLAGS=-Wl,-s => LDFLAGS=-Wl

Same linker error with similar error message. The fix proposed worked.
