The trick is to use "CONFIG_USE_PRIVATE_LIBGCC=y" instead of
"CONFIG_USE_PRIVATE_LIBGCC=yes" because it is handled like a boolean
Kconfig symbol.

BTW: I'm using env scripts for different toolchains which could be
sourced. For ELDK-5.5 I have:

$ cat env-eldk5.5-mips
export CONFIG_USE_PRIVATE_LIBGCC=y
export USE_PRIVATE_LIBGCC=yes
export
CROSS_COMPILE=/opt/eldk-5.5/mips/sysroots/i686-eldk-linux/usr/bin/mips-linux/mips-linux-
