cmake: use *dynamic* fxSDK compiler path as default for gint

Browse source 
Previously FXSDK_COMPILER_INSTALL would be stored as the install prefix.
However, this prefix is subject to unannounced changes when the compiler
version is upgraded without reconfiguring the fxlibc, which happens in
the GiteaPC workflow.

This commit avoids the use of CMAKE_INSTALL_PREFIX when using gint with
no specified prefix, and instead uses another cached variable which
leaves the prefix to be dynamically resolved based on the uncached
variable FXSDK_COMPILER_INSTALL, like most repositories do (eg. gint).
We need the cached indicator because we frequently reconfigure and
CMAKE_INSTALL_PREFIX_INITIALIZED_TO_DEFAULT is not persistent.
