scripts: fix sysroot prefix dir

The sysroot prefix dir was broken in #4960f5d9f829 due to a mishap
when making the out-of-sysroot lib/ symlink: the './' was mistakenly
changed into a single '.' .

Although Jonathan suggested restoring the missing '/' to restore it to
normal operation, I prefered using an explicit pushd/popd to be extra
sure of the symlink location and target, along with a fix in the sysroot
relative directory calculation.

      This configures how gcc will emit load-link, store-conditional and
yann@2523
    12
      sync opcodes. Normally, you'd set this to 'M', and configure will do
yann@2523
    13
      the correct thing (ie. enable llsc for Linux-based targets, disable
yann@2523
    14
      for others). If you know better, you can force either using llsc or
yann@2523
    15
      not using it (resp. 'Y' or 'N').

      This configures how gcc will emit the synci opcode. Normally, you'd

      This configures gcc to use copy relocations & PLTs. These are
yann@2523
    32
      extensions to the traditional SVR4-based MIPS ABIs and require
yann@2523
    33
      support from GNU binutils and the runtime C library.

      Say 'N' to keep the default and not use them, say 'Y' to use them.
