>Description:
ftp/curl does not configure when CPUTYPE is set in /etc/make.conf:

. elif ${CPUTYPE} == "armv6" <-- here MACHINE_CPU==arm
_CPUCFLAGS = -march=${CPUTYPE} -DARM_ARCH_6=1

This triggers a check for -D in CFLAGS in m4/xc-val-flags.m4 , function _XC_CHECK_VAR_CFLAGS, resulting
in this error message:

"CFLAGS error: CFLAGS may only be used to specify C compiler flags, not macro definitions. Use CPPFLAGS for: -DARM_ARCH_6=1"


>How-To-Repeat:
See above
>Fix:
A quick fix would be to remove lines 3629 through 3631 of configure, but it would be better to fix the m4 file.
