ldd: use direct exec mode unconditionally
Trying to exec malformed or unusual binary, for instance, a
non-FreeBSD
ABI, or using a non-standard interpreter, might give unexpected
outcome.

This appears to break things for armv7 (running on aarch64).
This manifests while building pfsense (for 3100 / armv7), which we do on
an aarch64 vm (to avoid having to deal with qemu, and because it’s
faster).
During that build a couple ports fail to build, including
databases/sqlite3.
It fails running `/usr/bin/ldd -a
"/wrkdirs/usr/ports/databases/sqlite3/work-default/stage/usr/local/bin/sqlite3"
"/wrkdirs/usr/ports/databases/sqlite3/work-default/stage/usr/local/lib/libsqlite3.so”`,
which produces:
ld-elf.so.1:
/wrkdirs/usr/ports/databases/sqlite3/work-default/stage/usr/local/bin/sqlite3:
mmap of entire address space failed: Cannot allocate memory
/wrkdirs/usr/ports/databases/sqlite3/work-default/stage/usr/local/bin/sqlite3:
exit status 1
That fails doing the `mapbase = mmap(base_addr, mapsize, PROT_NONE,
base_flags, -1, 0);` call in rtld-elf’s map_object():217. That call
does `mmap(0x10000, 0x1dc000, PROT_NONE, 0x6010, -1, 0) => 0xffffffff`.
With this patch reverted we can build successfully.
Best regards,
Kristof
