src/make.bash: Always check for the linker/loader Alpine Linux is not 

the only musl-based Linux distribution. Checking for /etc/alpine-release
excludes many other distributions (Oasis, KISS, Sabotage, sta.li). Not
having the correct GO_LDSO set during go builds will result in the wrong
linker/loader on nonalpine musl systems for pie builds. Instead, the
dynamic loader should be checked for every system and set. This results
in the correct dynamic linker being found on glibc systems
(/lib/ld-linux-x86-64.so.2 on Arch) and musl systems
(/lib/ld-musl-x84_64.so.1 on KISS).
