Makefile: remove the options target

The Makefile used to suppress output (by using @), so this target made sense at
the time.

But the Makefile should be simple and make debugging with less abstractions or
fancy printing.  The Makefile was made verbose and doesn't hide the build
output, so remove this target.

Prompted by a question on the mailing list about the options target.

+.SH NAME
+stest \- filter a list of files by properties
+.SH SYNOPSIS
+.B stest
+.RB [ -abcdefghlpqrsuwx ]
+.RB [ -n
+.IR file ]
+.RB [ -o
+.IR file ]
+.RI [ file ...]
+.SH DESCRIPTION
+.B stest
+takes a list of files and filters by the files' properties, analogous to
+.IR test (1).
+Files which pass all tests are printed to stdout. If no files are given, stest
+reads files from stdin.
+.SH OPTIONS
+.TP
+.B \-a
+Test hidden files.
+.TP
+.B \-b
+Test that files are block specials.
+.TP
+.B \-c
+Test that files are character specials.
+.TP
+.B \-d
+Test that files are directories.
+.TP
+.B \-e
+Test that files exist.
+.TP
+.B \-f
+Test that files are regular files.
+.TP
+.B \-g
+Test that files have their set-group-ID flag set.
+.TP
+.B \-h
+Test that files are symbolic links.
+.TP
+.B \-l
+Test the contents of a directory given as an argument.
+.TP
+.BI \-n " file"
+Test that files are newer than
+.IR file .
+.TP
+.BI \-o " file"
+Test that files are older than
+.IR file .
+.TP
+.B \-p
+Test that files are named pipes.
+.TP
+.B \-q
+No files are printed, only the exit status is returned.
+.TP
+.B \-r
+Test that files are readable.
+.TP
+.B \-s
+Test that files are not empty.
+.TP
+.B \-u
+Test that files have their set-user-ID flag set.
+.TP
+.B \-v
+Invert the sense of tests, only failing files pass.
+.TP
+.B \-w
+Test that files are writable.
+.TP
+.B \-x
+Test that files are executable.
+.SH EXIT STATUS
+.TP
+.B 0
+At least one file passed all tests.
+.TP
+.B 1
+No files passed all tests.
+.TP
+.B 2
+An error occurred.
