 Ok, I was told to ignore objdump/readelf output and just use file(1)
 instead, and this indeed shows we create proper eabi and oabi object
 files:
 
 src/compat/arm/oabi/lib/csu> file crt0.o 
 crt0.o: ELF 32-bit LSB relocatable, ARM, version 1, not stripped
 
 vs.:
 
 src/lib/csu/crt0.o: ELF 32-bit LSB relocatable, ARM, EABI5 version 1 (SYSV), not stripped
 
 So the cc options are fine, but we die trying to build the compat/oabi version
 of libgcc:
 
 /ssd/tools/lib/gcc/armv4--netbsdelf-eabi/4.8.4/../../../../armv4--netbsdelf-eabi
 /bin/ld: error: Source object libgcc_s_pic.a(_udivsi3.pico) has EABI version 0, 
 but target libgcc_s.so.1.0 has EABI version 5
