Meson build system enable by default -Wl,--as-needed [1][2] in the linker command line
and due to this the libmesa_dri_drivers.so build fail with the Codesourcery ARM and
Aarch64 2014.05 toolchain:
/home/buildroot/autobuild/run/instance-1/output-1/host/bin/arm-none-linux-gnueabi-g++

This problem seems to be specific to this toolchain release (ARM and aarch64)
CodeSourcery 2014.05: gcc 4.8.3-prerelease; binutils 2.24.51.20140217; glibc 2.18
The following prebuilt toolchain has been tested and doesn't trigger this issue:
Linaro 4.9-4.9-2014.11: gcc 4.9.3; binutils 2.24.0; glibc 2.19
CodeSourcery 2014.11: gcc 4.9.1; binutils 2.24.51.20140217; glibc 2.20
Older toolchains doesn't have a recent enough glibc or linux-headers version
to breaking the build with mesa3d 20.1.0 or libdrm 2.4.102.
In order to build mesa3d with the CodeSourcery 2014.05 using --as-needed would be
reorder the static librairies:
diff --git a/src/mesa/drivers/dri/meson.build b/src/mesa/drivers/dri/meson.build
index b09ca16e38a..9ac6731c522 100644

Instead, we can disable --as-needed from the meson build system using
"-Db_asneeded=false" only for this toolchain.
