bug#6181: 24.0.50; configure fails to detect necessary startup files on netbsd and possibilly on openbsd

[enami tsugutomo]

If opsys is netbsd (or openbsd), configure trys to check the existense
of file crti.o under the directory $CRT_DIR.  But since the shell
expression written in the script is wrong ($(var) is not variable
reference but command substitution), it fails to detect the existense.

As a result, generated src/temacs is not executable at least on netbsd.
It looks like there is confusion between makefile syntax and shell
script syntax.

Here is a diff to configure (of course actual fix should be done in
configure.in though):
