After the commit 9e4d308cd5, the performance of read from non-cygwin
pipe has been degraded. This is because select_sem mechanism does not
work for non-cygwin pipe. This patch fixes the issue.
Fixes: 9e4d308cd5 ("Cygwin: pipe: Adopt FILE_SYNCHRONOUS_IO_NONALERT
flag for read pipe.")

Commit 188d5f6c9a erroneously moved the mcountFunc.S file to the
TARGET_FILES target, rather than keeping it in GMON_FILES. The
result is that the __fentry__ entry point is now entirely undefined,
so `gcc -pg' is broken.
Create new target-specific GMON_TARGET_FILES and move mcountFunc.S
into it. Add $(GMON_TARGET_FILES) to GMON_FILES.
