To investigate, I said:

%nm *.o | grep getopt_long
0000006c T _getopt_long_only_r
00000024 T _getopt_long_r
00000000 T rpl_getopt_long
00000048 T rpl_getopt_long_only

I've seen this problem before in a 4.11 freebsd. This one is a
4.7-RELEASE-p28. As a quick hack, I wrote

#define getopt_long rpl_getopt_long

in the first line of lib-src/etags.c.

and ``make boostrap'' again: etags is built. But now b2m isn't:

gcc -I/usr/X11R6/include -I/usr/local/include -L/usr/local/lib    
-DHAVE_CONFIG_H    -I. -I../src -I/home/dbastos/tmp/emacs/lib-src 
-I/home/dbastos/tmp/emacs/lib-src/../src -Wl,-znocombreloc -L/usr/X11R6/lib 
-I/usr/X11R6/include -I/usr/local/include -L/usr/local/lib -g -O2 
/home/dbastos/tmp/emacs/lib-src/b2m.c  -DVERSION="\"22.1.50\""     getopt.o 
getopt1.o -lutil    -lc -o b2m
/tmp/ccRidQMZ.o: In function `main':
/home/dbastos/tmp/emacs/lib-src/b2m.c(.text+0x9a): undefined reference to 
`getopt_long'

So I added

#define getopt_long rpl_getopt_long

in the first line of lib-src/b2m.c. Then I said ``make'' and the build
process finished.
