According to my Poudriere build logs, the last successful build I was able to 
do of ruby21 for FreeBSD/arm 11-CURRENT was on 2015-08-07 (ruby21-2.1.6,1).  
That was using FreeBSD clang version 3.6.1 (tags/RELEASE_361/final 237755) 
20150525.

I have no successful builds since the update to FreeBSD clang version 3.7.0 
(tags/RELEASE_370/final 246257) 20150906.  It fails with the same error you 
report above.

Cheers,

Paul.

Right, but that is not the real problem.  Earlier on, the configure
script is checking for the regular _setjmp():

configure:16921: checking for _setjmp
configure:16921: cc -o conftest -O -pipe  -fno-strict-aliasing 
-I/usr/local/include   -fstack-protector conftest.c -lcrypt -lm -lpthread 
-L/usr/local/lib >&5
conftest.c:228:6: warning: declaration of built-in function '_setjmp' requires 
inclusion of the header  [-Wbuiltin-requires-header]
char _setjmp ();
 ^
conftest.c:239:17: error: too few arguments to function call, expected 1, have 0
return _setjmp ();
   ~^
1 warning and 1 error generated.
configure:16921: $? = 1
configure: failed program was:

As to why GNU configure tries to call this without arguments, is beyond
me.  To work around its brokenness, I would set ac_cv_func__setjmp to
yes before calling configure.  Or attempt to unbreak autoconf, but that
is a truly Herculean task. :-)

The whole file is available as http://space.kvedulv.de/ruby_arm_config.log, the 
output
from the specific test is:

conftest.c:340:20: error: __builtin_longjmp is not supported for the current 
target
void t(void) {__builtin_longjmp((void **) jb, 1);}
  ^~
conftest.c:341:29: error: __builtin_setjmp is not supported for the current 
target
int jump(void) {(void)(__builtin_setjmp((void **) jb) ? 1 : 0); 
return 0;}
   ^~
