This gives me a good place to start tracking the changes. According to 
the ARM ELF spec, DT_TEXTREL isn't used. Glibc's ld-so (2.3.2) has a 
comment "DT_TEXTREL is now in Level 2 and might phase out at some 
time." which I think means it's deprecated. Between your version and 
mine, someone might have axed it.

D'oh! Fat fingered cut'n'paste error. I keep going back and forth on 
whether it's the linker or the assembly responsible for TEXTREL but 
both return the same version.

If I'm reading this correctly, it's changing 
"link_info.combreloc=false" to "link_info.combreloc=true" in 
ld/ldmain.c (not sure the effect but mine is already =true) and 
changing the interpreter path to the ld-so.

Thanks. I'm off to ftp and diff a few binutils releases.
