[PATCH v2] h8300: Makefile: add "-no-warn-mismatch" to linker toavoid linking error.

From: Chen Gang
Date: Tue Aug 27 2013 - 01:36:49 EST


Need add "-no-warn-mismatch" to avoid the linking error, or assembly
files which are outside of the "arch/h8300" can not pass compiling.

The related error (allmodconfig for h8300):

/usr/local/bin/h8300-gchen-elf-ld: h8300 architecture of input file `usr/initramfs_data.o' is incompatible with h8300h output
/usr/local/bin/h8300-gchen-elf-ld: h8300 architecture of input file `kernel/modsign_certificate.o' is incompatible with h8300h output

The cross-compiler's information:

[root@dhcp122 linux-next]# /usr/local/bin/h8300-gchen-elf-ld -v
GNU ld (GNU Binutils) 2.22
[root@dhcp122 linux-next]# /usr/local/bin/h8300-gchen-elf-as -v
