The option BR2_TOOLCHAIN_EXTERNAL_SYNOPSYS_ARC just depends on
BR2_arc, but the choice of toolchains that appears once
BR2_TOOLCHAIN_EXTERNAL_SYNOPSYS_ARC=y only has choices for:
depends on BR2_arc750d || BR2_arc770d
and
depends on BR2_archs38_64mpy || BR2_archs38_full || \
BR2_archs4x_rel31 || BR2_archs4x
which means that if you have a BR2_archs38=y configuration, you end up
with no choice of toolchain, and the build fails with "No C library
selected". Fix this by making sure BR2_TOOLCHAIN_EXTERNAL_SYNOPSYS_ARC
can only be selected when an actual toolchain is available.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC.
