libgcc.a is compiled when egcs is compiled.
I did build the kernel for uclinux for a big endian arm and was compelled to
rebuild the egcs the following way ; it may not be correct but I did not find
any other way to succeed :
mkdir build-egcs
cd build-egcs
../egcs/configure --target=... -prefix=...
then I edit the /build-egcs/Makefile and /build-egcs/gcc/Makefile where I modify
GCC_FOR_TARGET with adding -mbig-endian option
make LANGUAGES="c c++"
make install
If there is a proper way to do it, please advise
Thank you
