           Summary: glibc fails to build on
                    buildroot-sh4*-buildroot-linux-gnu

          Priority: P5
         Component: Other
          Assignee: unassigned at buildroot.uclibc.org

  Target Milestone: ---

glibc fails to build on buildroot-{sh4,sh4a,sh4eb,sh4aeb}-buildroot-linux-gnu,
see below.

Tested on git as of today (2b2e216ee0cb6894b0012316c20da9291ce14458):
 - make menuconfig
 - Select sh4
 - Select "Build options -> libraries (both shared and static)"
 - Select "Toolchain -> C library (glibc)" (default version 2.24)
 - Select "Toolchain -> Enable C++ support"

Everything else is default. Trying other versions of glibc doesn't seem to make
any difference. It seems to happen on all sh4* variants apparently, though some
more testing might be required there. Host gcc is 6.3.0.
