Oh, and you asked for the make invocation as well.  It's

make --output-sync=line -j2 'LDFLAGS=-Wl,-O1 -Wl,--as-needed'
LIBPATH=/usr/lib/gcc/aarch64_be-unknown-linux-gnu/14 'STAGE1_CFLAGS= -pipe -O2'
'STAGE1_CXXFLAGS= -pipe -O2' 'STAGE1_LDFLAGS= -Wl,-O1 -Wl,--as-needed'
'BOOT_CFLAGS= -pipe -O2' 'BOOT_LDFLAGS= -Wl,-O1 -Wl,--as-needed'
'LDFLAGS_FOR_TARGET=-Wl,-O1 -Wl,--as-needed' bootstrap-lean
