Replace crt1.o with gcrt1.o when -pg is specified
Clang linker driver links the wrong crt1.o file when -pg option is specified.
As a result, the gprof doesn't work with clang on Linux. Programs compiled with
clang -pg doesn't generate gmon.out file.
Attached is patch which replaces crt1.o with gcrt1.o when -pg is specified.
With the patch, compiled programs generate gmon.out file correctly.</pre>
