[Bug 264192] lang/ghc: poudriere based build used odd mix of devel/llvm10 and system toolchain

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=264192

            Bug ID: 264192
           Summary: lang/ghc: poudriere based build used odd mix of
                    devel/llvm10 and system toolchain
           Product: Ports & Packages
           Version: Latest
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: Individual Port(s)
          Assignee: ports-bugs@FreeBSD.org
          Reporter: marklmi26-fbsd@yahoo.com

There is a lang/ghc build oddity:
watching it in top during the early parts
of its build shows:

52498    . . . /usr/local/llvm10/bin/llc -O1 -enable-tbaa
-relocation-model=static -mcpu=generic -mattr=+strict-align /tmp/ghc47452_0/gh

so it is using devel/llvm10 at this stage.

I see in the Makefile :

LLVM_VERSION=           10
BOOT_GHC_VERSION=       8.10.7
# LLVM version that bootstrap compiler uses
BOOT_LLVM_VERSION=      10
. . .
.if ${ARCH} == aarch64 || ${ARCH:Marmv*}
# ghc-8.10.x on arm requires devel/llvm10
# CONFIGURE_TARGET must to be the same as the llvm triple
CONFIGURE_TARGET=       ${ARCH}-unknown-freebsd${"${ARCH:Maarch64}" !=
"":?:-gnueabihf}
CONFIGURE_ARGS+=        --host=${CONFIGURE_TARGET}
BUILD_DEPENDS+=         llc${LLVM_VERSION}:devel/llvm${LLVM_VERSION}
RUN_DEPENDS+=           llc${LLVM_VERSION}:devel/llvm${LLVM_VERSION}

# When GHC being compiled and GHC used for bootstrapping support different
# LLVM versions, we have to pull in both. Luckily, this is relatively rare.
.  if ${BOOT_LLVM_VERSION} != ${LLVM_VERSION}
BUILD_DEPENDS+=         llc${BOOT_LLVM_VERSION}:devel/llvm${BOOT_LLVM_VERSION}
.  endif
.endif

Yet the log file for lang/ghc shows, for only
some of its activity, far from all:

I'll stop with that. There is more.

The log files for lang/ghc show:

but no other devel/llvm* install. So the use of
llvm14 was via the system toolchain, not via
use of devel/llvm14 .

For reference . . .

The /usr/ports content vintage in use:

The aarch64 system (being used to target armv7 in the build):
(system can execute armv7 code natively, so no use of qemu)
