libilclient.a in hardffp not hardfp

[shirro]

Building and making demos in hardfp/opt/vc/src/hello_pi produces errors about attempting to pass args with VFP registers to libilclient.a suggesting it is compiled with the softfloat abi. readelf -A and disassembly appear to confirm this is the case.

[hexameron]

There are two copies of libilclient.a in the hardfp tree, and makefile.include explicitly links the softfp copy.
