When ld is lld net/ipxe fails to build with

ld  -m elf_i386_fbsd -N --no-check-sections --section-start=.prefix=0   --gc-sections -static -o bin/usbdisk.bin --oformat binary -e 0 bin/usbdisk.o
ld: error: unknown argument: --no-check-sections
ld: error: unknown argument: --section-start=.prefix=0

The port is supposed to use ld from devel/binutils but does not
currently respect ${LD} (or any of the other binutils related
variables) and always uses ld from base.  Make sure that the build
actually uses the binutils from ports.

While here:
- Remove Perl runtime dependency
- Pet portlint
- Trim the pkg-message to the actually useful bits
