security/nss (from head -r515742): build failure for poudriere-devel based amd64->armv7 (cortex-a7) cross build, it tried to build aes-armv8.c and failed

[Mark Millard]

For some reason security/nss tried to build "-march=armv8-a -mfpu=crypto-neon-fp-armv8 aes-armv8.c"
material when targeting armv7 (cortex-a7). This did not go well . . .
