commit 3cf386984c1870c2b39ec3fb47b0deb7b30535c3
Author: Mark Wielaard <mark@klomp.org>

    libelf: Check for mremap, elf_update needs it for ELF_C_RDWR_MMAP

    Add a AC_CHECK_FUNCS configure check for mremap. Some systems like
    KFreeBSD and the Hurd don't have it. Also add a configure warning
    because without mremap elf_update will often fail when ELF_C_RDWR_MMAP
    is used. ELF_C_RDWR_MMAP is an elfutils extension to libelf.

    Signed-off-by: Mark Wielaard <mark@klomp.org>

Note that various tests will FAIL without mremap:

FAIL: run-bug1-test.sh
FAIL: elfstrtab
FAIL: emptyfile
FAIL: run-copyadd-sections.sh

elf_update: cannot write data to file
