- disables --bootstrap-mode where it was enabled, except for test1000
which needs to build in bootstrap-mode to check that M2-Planet can be
compiled by cc_*
- the only hold-out is test0021 which needs getcwd which is missing in
M2libc
- note that test0106 needs a fix to fgetc or it will never notice it has
reached the end of stdin
The close syscall was missing an indirection and therefore closed random
file descriptors (very visible in strace output).
Test 0104 did not properly null terminate the envp, resulting in -EFAULT
on execve syscall in case the next value in memory does not happen to be
0 (which it seems to be right now).
