Not many uses for soft float - Pi and most everyone else has moved to hard float for the aprox 10% gain in performance.
The instructions on the Wiki deal with creating a tool chain for hard float and then building with it.

Due to the relative lack of interest in soft float, I have not spent much time working on the soft float side.
To work around this (at least to start, I don't have time to check it fully out at the moment)

you would want to create a soft float toolchain using buildSrc/crosslibs/crosslibs-armv6sf.sh, which you said you did :-)

That should create ../crosslibs. In there create a directory arm-linaro-4.7. That should shut up the error message.
But... you will still need a cross compiler installed. So you can either make that directory a link to your cross compiler, or you can use the gradle magic override you can find in armv6sf.gradle:

if (rootProject.hasProperty("ARMV6SF_COMPILER")) {
     logger.quiet "Using alternate ARMV6SF_COMPILER $rootProject.ARMV6SF_COMPILER"
     compilerHome=file(rootProject.ARMV6SF_COMPILER);
}
if (rootProject.hasProperty("ARMV6SF_COMPILER_PREFIX")) {
     logger.quiet "Using alternate ARMV6SF_COMPILER_PREFIX $rootProject.ARMV6SF_COMPILER_PREFIX"
     compilerPrefix="${rootProject.ARMV6SF_COMPILER_PREFIX}"
}

So you would add -PARMV6SF_COMPILER=/path_to_your_cross_compiler -PARMV6SF_COMPILER_PREFIX="arm-linux-gnueabi-"
to your gradle line, changing stuff as needed.

There are still some packages I am missing for a full Fedora 21 build related to desktop media, but the core builds fine now. (Any Fedora users out there that want to help me find the right media development packages ?)

There has been a lot of work in ARM (Monocle, touch, and 3D) that has not made it into an official ARM bundle.
