I want to port U-boot to my custom Pentium 2 board, so I do a test compile of sc520_cdp config first, but can not pass when linking.

OS: Redhat 7.3 on X86 gcc: 2.96-110 binutils: 2.11.93

step: make distclean make sc520_cdp_config make ERROR: ld: section .data [387f6e00 -> 387f7fa3] overlaps section .rodata.str1.1 [387f6e00 -> 387f868d] ld: section .realmode [387f7fa4 -> 387f8109] overlaps section .rodata.str1.1 [387f6e00 -> 387f868d] ld: section .bios [387f810a -> 387f831b] overlaps section .rodata.str1.1 [387f6e00 -> 387f868d] make: *** [u-boot] Error 1

why? how to correct this problem?? thanks a lot!!!!
