Compiling u-boot-rpi3 on an rpi3

[bob prohaska]

With FreeBSD at r347055 and ports at 500862 attempts to compile
sysutils/u-boot-rpi3 stop with a string of errors starting with
ld: error: undefined symbol: EVP_MD_CTX_new
>>> referenced by mxsimage.c
>>>               tools/mxsimage.o:(mxsimage_generate)

ld: error: undefined symbol: EVP_MD_CTX_free
>>> referenced by mxsimage.c
>>>               tools/mxsimage.o:(mxsimage_generate)

ld: error: undefined symbol: EVP_MD_CTX_new
>>> referenced by mxsimage.c
>>>               tools/mxsimage.o:(mxsimage_generate)

ld: error: undefined symbol: EVP_CIPHER_CTX_reset
>>> referenced by mxsimage.c
>>>               tools/mxsimage.o:(mxsimage_generate)

Is there a fix or workaround?

Thanks for reading,
