I tried brandelfing, but that didn't work. There's some weird symbols
in there:
00000000 DF *UND* 00000023 GLIBC_2.0 fprintf
00000000 DF *UND* 000000f8 GLIBC_2.0 fflush
00000000 DF *UND* 000001b4 GLIBC_2.0 malloc
00000000 DF *UND* 00000058 GLIBC_2.0 memmove
00000000 DO *UND* 00000004 GLIBC_2.0 stderr
00000000 DF *UND* 0000020d GLIBC_2.0 abort
00000000 DF *UND* 00000027 GLIBC_2.0 memcpy
00000000 w DF *UND* 000000ac GLIBC_2.1.3 __cxa_finalize
00000000 DF *UND* 00000043 GLIBC_2.0 memset
So it looks like I'm close... objcopy -R kept the GLIBC_* references
in place, alas, so that didn't work, as suggested elsewhere in this
thread.
The above list is small, but has hree bad entries: fprintf, fflush and
stderr. So that may present a problem for me if these functions are
ever called.
