arm vfp glibc error.

Hi,

I'm trying to build an arm toolchain with VFP support using 
crosstool-0.38.  The toolchain components are:

- binutils-2.16.1
- gcc-4.0.2
- glibc-2.3.5
-linux-libc-headers-2.6.12.0

Additional toolchain configuration:

- BINUTILS_EXTRA_CONFIG="--with-fp=vfp"
- GCC_EXTRA_CONFIG="--with-fp=vfp"
- GLIBC_EXTRA_CONFIG="--with-fp=vfp"

The toolchain build completes successfully, but when I try to build a 
test program with the flags: "-mfpu=vfp -mfloat-abi=soft" it fails with 
a linker error: "ld: cannot find -lfloat"

Are there some flags missing that should be passed on the command line, 
or is there a configuration option to glibc to enable VFP support?

Best regards,

Steve
