 This fixes the build problem on i386 (although we're stuck with
 possible run-time problems when numpy is built with the newer binutils
 until the latest fenv.h changes are backported to all supported
 versions of FreeBSD), but this code is machine-dependent, and fenv.h
 needs to be selected based on ARCH.
 
 You might do instead something like:
 
 ...
 .if exists(${LOCALBASE}/bin/as)
 .if ${ARCH} == "i386"
 FP_ARCH= i387
 .else
 FP_ARCH= ${ARCH}
 .endif
 MASTER_SITES+= http://svn.freebsd.org/base/head/lib/msun/%SUBDIR%/:fp
 MASTER_SITE_SUBDIR+= ${FP_ARCH}/:fp
 DISTFILES+= fenv.h:fp
 .endif
 ...
   pre-configure:
  .if exists(${LOCALBASE}/bin/as)
      ${CP} ${DISTDIR}/fenv.h ${WRKSRC}/numpy/core/include/numpy/fenv/fenv.h; \
      ${PATCH} ${PATCH_DIST_ARGS} < ${FILESDIR}/fenv.patch; \
 .endif
 ...
