You don’t need these symlinks.
To use arm-eabi-gcc as your cross compiler, you want to use
gmake … CROSS_COMPILE=arm-eabi- ...
and make sure /usr/local/bin is part of your PATH.
U-Boot build scripts use ${CROSS_COMPILE}gcc to run the cross-compiler GCC, so if you set CROSS to arm-eabi-, U-Boot will use arm-eabi-gcc as the cross compiler.

This is bad. U-Boot by default uses HOSTCC=gcc to run a compiler that can build tools to run on the host machine. But you’ve set up ‘gcc’ to run the cross-compiler, which is why HOSTCC builds are failing.

No. scripts/basic/fixdep requires sys/mman.h when it
is compiled using HOSTCC. But you’ve broken HOSTCC.
