Yes, absolutely.

You mean in /usr/arm-softfloat-linux-uclibc/etc/make.conf ?
Yes.
The make.conf at that location is
ACCEPT_KEYWORDS="arm"
ARCH="arm"
CFLAGS="-Os -pipe -mfloat-abi=softfp -mfpu=vfp"
CHOST="arm-softfloat-linux-uclibc"
CXXFLAGS="${CFLAGS}"
GENTOO_MIRRORS="http://open-systems.ufl.edu/mirrors/gentoo
http://prometheus.cs.wmich.edu/gentoo http://mirror.datapipe.net/gentoo
http://ftp.ucsb.edu/pub/m$
INPUT_DEVICES="keyboard"
MAKEOPTS="-j2"
USE="minimal symlink"
UCLIBC_CPU="ARM920T"
