In GCC 9 support for the Armv5 and Armv5E architectures (which have no known implementations) has been removed, cf. https://gcc.gnu.org/gcc-9/changes.html

Commit 16540d07fd62 ("arm: fix -march for ARM11") changed the value of the compiler flag from -march=armv5 and -march=armv5t into -march=armv6 for ARM11.

The values prior to this patch were:

arch-$(CONFIG_CPU_ARM1136)     =-march=armv5
arch-$(CONFIG_CPU_ARM1176)     =-march=armv5t

The change lead to a regression with the Raspberry Pi Zero W not booting anymore.

Use -march=armv5t both for ARM1136 and ARM1176.
