BUG: mips: errors when compiling kernel with a large initramfs

Hi,
It fails to compile mips kernel with large initramfs (at link time).
kernel version: 5.6.0
Steps to reproduce:
1. git clone mainline kernel
2. set ARCH=mips and CROSS_COMPILE=mips-linux-gnu-
3. make defconfig
4.enable initramfs support and set the path about initramfs source file
5.make -j24
[KEY] when your initramfs files is too large, and cause
usr/initramfs_data.cpio.gz
compiled is larger than 225M, you will get the following error. BTW, x86
doesn't
have this issue that I have tested.
