The linker string merging code is not working with the asm directives, it
doesn't really care what part of the string comes from .string or .ascii and
what part comes from .zero directives.  And, what do you find wrong on the
alignment?
The section name indicates 8 byte alignment and .align 3 directive (which is
like .balign 8 on this target) says the alignment of the strings is 8 byte, so
all the strings (including a single terminating '\0') must be padded to
multiples of 8 bytes by zeros.
