>Description:
On NetBSD/evbearmv6hf-el for Raspberry Pi, MACHINE_ARCH is "earm".

$ cd /usr/pkgsrc
$ $ make -V MACHINE_ARCH
earm

But in base's /usr/share/mk/bsd.own.mk, there is the following code.

#
# Default mips64 to softfloat now.
# arm is always softfloat unless it isn't
# emips is always softfloat.
# coldfire is always softfloat
#
.if ${MACHINE_ARCH} == "mips64eb" || ${MACHINE_ARCH} == "mips64el" || \
    (${MACHINE_CPU} == "arm" && ${MACHINE_ARCH:M*hf*} == "") || \
    ${MACHINE_ARCH} == "coldfire" || \
    ${MACHINE} == "emips"
MKSOFTFLOAT?=   yes
.endif

Then softfloat is enabled on evbearmv6hf-el (hardfloat) system.

This inconsistency causes build failure of pkgsrc/sysutils/checkperms,
very essential program for pkgsrc developers (and many programs, I believe).
Error message is the following.

#   compile  checkperms-1.11/checkperms.o

*** Error code 1
 

Please fix softfloat/hardfloat detection mechanism on earm.

See above.

I have no idea.
