Comment (by AlainODea):

 Here are the "WARNING" messages from the log.

 This seems likely to be problematic, not sure what I've done wrong with
 it:

 {{{
 checking for x86_64-unknown-linux-gnu-ranlib... no
 checking for ranlib... ranlib
 configure: WARNING: using cross tools not prefixed with host triplet
 }}}

 This seems to be mostly harmless, but I can work around it by install
 packages with xmllint, xsltproc, and dblatex on my build system:

 {{{
 checking for xmllint... no
 configure: WARNING: cannot find xmllint in your PATH, you will not be able
 to validate your documentation
 checking for xsltproc... no
 configure: WARNING: cannot find xsltproc in your PATH, you will not be
 able to build the HTML documentation
 checking for dblatex... no
 configure: WARNING: cannot find dblatex in your PATH, you will not be able
 to build the PDF and PS documentation
 }}}

 This suggests that I need to include more in my $SYSROOT for my cross-
 compiler:

 {{{
 checking nlist.h presence... no
 configure: WARNING: nlist.h: accepted by the compiler, rejected by the
 preprocessor!
 configure: WARNING: nlist.h: proceeding with the compiler's result
 }}}

 This is a fallback I guess:

 {{{
 checking for working fork... cross
 configure: WARNING: result yes guessed because of cross compilation
 }}}

 This looks very problematic:

 {{{
 checking sys/eventfd.h presence... yes
 configure: WARNING: sys/eventfd.h: present but cannot be compiled
 configure: WARNING: sys/eventfd.h:     check for missing prerequisite
 headers?
 configure: WARNING: sys/eventfd.h: see the Autoconf documentation
 configure: WARNING: sys/eventfd.h:     section "Present But Cannot Be
 Compiled"
 configure: WARNING: sys/eventfd.h: proceeding with the compiler's result
 configure: WARNING:     ## -----------------------------------------------
 ##
 configure: WARNING:     ## Report this to glasgow-haskell-bugs at haskell.org
 ##
 configure: WARNING:     ## -----------------------------------------------
 ##
 }}}

 This is potentially the cause of #8366:

 {{{
 Configuring terminfo-0.3.2.5...
 configure: WARNING: unrecognized options: --with-compiler, --with-gcc
 }}}

 {{{
 config.status: creating terminfo.buildinfo
 configure: WARNING: unrecognized options: --with-compiler, --with-gcc
 }}}

 {{{

 configure: WARNING: unrecognized options: --with-compiler, --with-gcc
 }}}

 {{{

 config.status: creating gmp/config.mk
 configure: WARNING: unrecognized options: --with-compiler, --with-gcc
 }}}

 {{{

 configure: WARNING: unrecognized options: --with-compiler, --with-gcc
 }}}

 {{{

 config.status: creating base.buildinfo

 config.status: creating include/EventConfig.h
 configure: WARNING: unrecognized options: --with-compiler, --with-gcc
 }}}

 {{{

 configure: WARNING: unrecognized options: --with-compiler, --with-gcc
 }}}

 {{{

 configure: WARNING: unrecognized options: --with-compiler, --with-gcc
 }}}

 {{{

 configure: WARNING: unrecognized options: --with-compiler, --with-gcc
 }}}

 Lots more of those.
