Hmmm, what does make -V LINKER_TYPE and make -V LINKER_FEATURES say? They look good for me, but the only way you get this error is if they are wrong. Although from your typescript, I see: ===> lib/libc (cleandir) make[4]: "/usr/home/bcran/workspace/freebsd/lib/libc/Makefile" line 26: amd64 libc requires linker ifunc support which tells me that we need to exclude all the non-build targets from this check.... This will use the HOST linker rather than the TARGET linker. So something like: diff --git a/lib/libc/Makefile b/lib/libc/Makefile index a1ce123c0f33..11575e1cabff 100644 --- a/lib/libc/Makefile +++ b/lib/libc/Makefile @@ -21,10 +21,12 @@ LIBC_ARCH=${MACHINE_ARCH} LIBC_ARCH=${MACHINE_CPUARCH} .endif +.if build(all) .if (${LIBC_ARCH} == amd64 || ${LIBC_ARCH} == i386) && \ defined(LINKER_FEATURES) && ${LINKER_FEATURES:Mifunc} == "" .error ${LIBC_ARCH} libc requires linker ifunc support .endif +.endif # All library objects contain FreeBSD revision strings by default; they may be # excluded as a space-saving measure. To produce a library that does may be needed, but the problem may be related to caching these values from the host as well, even though we rebuild them...
