May be the following will help. It shows a clear difference
between the ${XLD} and ${LD} text that is used in:
.if ${ld} == "LD" || (${ld} == "XLD" && ${XLD} != ${LD})
when ${LD} == "XLD" in my context.
My src config that is involved has (extracted):
TO_TYPE=powerpc64
VERSION_CONTEXT=12.0
CROSS_TOOLCHAIN=${TO_TYPE}-gcc
X_COMPILER_TYPE=gcc
CROSS_BINUTILS_PREFIX=/usr/local/${TOOLS_TO_TYPE}-unknown-freebsd${VERSION_CONTEXT}/bin/
.if ${.MAKE.LEVEL} == 0
XLD=/usr/local/${TOOLS_TO_TYPE}-unknown-freebsd${VERSION_CONTEXT}/bin/ld
.export XLD
.endif
and is used via:
SRCCONF="/dev/null"
SRC_ENV_CONF="/root/src.configs/src.conf.powerpc64-xtoolchain-gcc.amd64-host"
Given that, by adding a:
.warning "ld=${ld} XLD=${XLD} LD=${LD} LINKER_TYPE=${${X_}LINKER_TYPE}
LINKER_VERSION=${${X_}LINKER_VERSION}"
line just before before the /usr/src/share/mk/bsd.linker.mk line:
_ld_version!= (${${ld}} --version || echo none) | head -n 1
that is being (incorrectly) executed and not finding head the
extra .warning reported:
make[4]: "/usr/src/share/mk/bsd.linker.mk" line 47: warning: "ld=XLD
XLD=/usr/local/powerpc64-unknown-freebsd12.0/bin/ld
LD=/usr/local/powerpc64-unknown-freebsd12.0/bin/ld -m elf32ppc_fbsd
LINKER_TYPE= LINKER_VERSION="
Note that the LD= part has the text:
-m elf32ppc_fbsd
in it where my explicit XLD assignment does not.
Is my src config handling of XLD non-supported in some way?
Did I step outside the intended coverage?
