Comment (by pkubaj):

 OK.
 You need FreeBSD sources in {{{/usr/src}}} and the current ports tree in
 {{{/usr/ports}}} (all on amd64).

 {{{
 cd /usr/src
 pkg install devel/powerpc64-xtoolchain-gcc
 make CROSS_TOOLCHAIN=powerpc64-gcc TARGET=powerpc TARGET_ARCH=powerpc64
 buildworld
 make CROSS_TOOLCHAIN=powerpc64-gcc TARGET=powerpc TARGET_ARCH=powerpc64
 installworld DESTDIR=/sysroots/powerpc64
 make CROSS_TOOLCHAIN=powerpc64-gcc TARGET=powerpc TARGET_ARCH=powerpc64
 distribution DESTDIR=/sysroots/powerpc64
 }}}

 Now you need wrappers for toolchain. I put mine to ~/bin:
 powerpc64-portbld-freebsd-ar:
 #!/bin/sh

 exec  /usr/local/bin/powerpc64-unknown-freebsd12.0-ar "$@"

 powerpc64-portbld-freebsd-g++:
 #!/bin/sh

 exec  /usr/local/bin/powerpc64-unknown-freebsd12.0-g++
 --sysroot=/sysroots/powerpc64 "$@"

 powerpc64-portbld-freebsd-gcc:
 #!/bin/sh

 exec  /usr/local/bin/powerpc64-unknown-freebsd12.0-gcc
 --sysroot=/sysroots/powerpc64 "$@"

 powerpc64-portbld-freebsd-ld:
 #!/bin/sh

 exec /usr/local/bin/powerpc64-unknown-freebsd12.0-ld
 --sysroot=/sysroots/powerpc64 "$@"

 powerpc64-portbld-freebsd-nm:
 #!/bin/sh

 exec  /usr/local/bin/powerpc64-unknown-freebsd12.0-gcc-nm "$@"

 powerpc64-portbld-freebsd-objdump:
 #!/bin/sh

 exec  /usr/local/bin/powerpc64-unknown-freebsd12.0-objdump "$@"

 powerpc64-portbld-freebsd-ranlib:
 #!/bin/sh

 exec /usr/local/bin/powerpc64-unknown-freebsd12.0-ranlib "$@"

 powerpc64-portbld-freebsd-strip:
 #!/bin/sh

 exec  /usr/local/bin/powerpc64-unknown-freebsd12.0-strip "$@"

 {{{
 cd /usr/ports/lang/ghc
 }}}

 Put your patches to {{{files}}}.

 {{{
 make patch
 cd work/ghc-8.6.3
 cp mk/build.mk.sample mk/build.mk
 }}}

 Add to mk/build.mk:
 {{{
 INTEGER_LIBRARY = integer-simple
 BIN_DIST_NAME=ghc-8.6.3-boot
 BIN_DIST_TAR=ghc-8.6.3-boot.tar
 DYNAMIC_GHC_PROGRAMS = NO
 }}}

 Then it doesn't build with dtrace):
 {{{
 ./configure --target=powerpc64-portbld-freebsd --disable-dtrace
 gmake
 gmake binary-dist TAR_COMP=xz
 mv ghc-8.6.3-boot-powerpc64-portbld-freebsd.tar.xz ghc-8.6.3-boot-
 powerpc64-freebsd.tar.xz
 }}}

 And copy ghc-8.6.3-boot-powerpc64-freebsd.tar.xz to my POWER box to
 {{{/usr/ports/distfiles}}}. On it, I have the same set of patches and a
 patch to {{{lang/ghc/bsd.ghc.mk}}}:

 You also need to add a proper SHA256 and SIZE entries to
 {{{lang/ghc/distinfo}}}:

 {{{
 SHA256 (ghc-8.6.3-boot-powerpc64-freebsd.tar.xz) =
 258f4d41d2cf7977f756e6a5ac718e5ed140065d31ba89c8aee4f654d57a6315
 SIZE (ghc-8.6.3-boot-powerpc64-freebsd.tar.xz) = 179817644
 }}}

 SHA256 is returned by {{{sha256}}} and SIZE is from {{{stat -f %z
 ghc-8.6.3-boot-powerpc64-freebsd.tar.xz}}}.

 Then:
 {{{
 cd /usr/ports/lang/ghc
 make (I disable all options to avoid further problems)
 }}}

 Then just wait for an error.












 Alternatively, you could mark a BOOT option, and install ghc locally like
 this.
 {{{
 cd /usr/ports/distfiles
 tar xvvf ghc-8.6.3-boot-powerpc64-freebsd.tar.xz
 cd ghc-8.6.3-boot
 CFLAGS="-Wl,-rpath=/usr/local/lib/gcc8 -isystem /usr/local/include"
 CXXFLAGS="-Wl,-rpath=/usr/local/lib/gcc8 -isystem /usr/local/include"
 CC=gcc8 CXX=g++8 ./configure
 gmake install
 }}}

 I hope it's clear enough :)
