So? Download the sources and build yourself an uncrippled version.

That is not so easy because MIPS is not the most common architecture.
I'm working on getting GCC 4.1.2 + Glibc + binutils compiled for MIPS
using crosstool but there are some problems with getting the right
versions together and using the proper settings.


I downloaded the Linux sources for the Linksys routers from their site,
it includes a working gcc for MIPS, I'v compiled the whole thing and wrote some MIPS
apps too, al seems to work just fine.

My Makefile looks like this (for making a kernel module):
TARGET := mmc
WARN := -W -Wall -Wstrict-prototypes -Wmissing-prototypes -fno-strict-aliasing -mips32

INCLUDE := -isystem /mnt/hdd4/linksys/WAP54Gv3_3_05_03_EN_GPL/release/src/linux/linux/include

CFLAGS := -O2 -DMODULE -D__KERNEL__ ${WARN} ${INCLUDE} -fno-pic -mno-abicalls -mlong-calls

CC := /opt/brcm/hndtools-mipsel-linux-3.2.3/mipsel-linux/bin/gcc

Note the definition of CC
You can download the stuff from the Linksys site (big).

Does this help?

Not really :-) I tried to use crosstool but I found out this is not a
tool to rely on for modern GCC compilers. I'm now trying
emdebian-tools from emdebian.org. Which seems to work! The reason I
want to get it compiled is because I'm trying to use gcc + glibc for
an embedded device without FPU together with buildroot.
