profiles: Mask glibc[stack-realign] on non-amd64/x86, default on amd64
The stack alignment issue affecting compatibility with older 32-bit
binaries is specific to amd64 and x86.
The workaround incurs a performance cost on the 32-bit build, so enable
the flag by default on amd64 but not on x86. Other popular distributions
always enable this workaround.
