From d22e3d69ee1a3f83ff7cc943af63de48b6156dcf Mon Sep 17 00:00:00 2001 From: Sudip Mukherjee Date: Tue, 3 Oct 2017 16:16:49 -0700 Subject: [PATCH] m32r: fix build failure The allmodconfig build of m32r is failing with the error: lib/mpi/mpih-div.o: In function 'mpihelp_divrem': mpih-div.c:(.text+0x40): undefined reference to 'abort' mpih-div.c:(.text+0x40): relocation truncated to fit: R_M32R_26_PCREL_RELA against undefined symbol 'abort' The function 'abort' was never defined for the m32r architecture. Create 'abort' as is done in other arch like 'arm' and 'unicore32'.
