With gcc-14 warnings caused by type mismatches turn to errors:
- (void **) needs explicit conversion operator to become
struct funcdesc_value **entry
- both subexpressions of the ternary operator must be pointers
- %p should be used instead of %x to print a pointer

In ARM_EABI mode, the pread64 syscall parameters are aligned on
64-bits. This syscall is used in rtld when processing FDPIC
relocations.
* ldso/include/dl-syscall.h (__syscall_pread): Fix definition.
(__dl_pread): Fix syscall invocation.
* ldso/ldso/fdpic/dl-sysdep.h (__DL_PREAD): Handle __NR_pread64.

Add FDPIC dynamic relocations support, similar to what other FDPIC
targets do.
Lazy binding is implemented in a folllow-up patch.
Disable the SEND* macros because they involve relocations to
access constant strings that are unsupported by the existing
arm version.
Define DL_START, START, ARCH_NEEDS_BOOTSTRAP_RELOCS,
DL_CHECK_LIB_TYPE similarly to what other FDPIC targets do.
Define raise() because _dl_find_hash references __aeabi_uidivmod,
which uses __aeabi_idiv0 which in turn references raise.
* include/elf.h (R_ARM_FUNCDESC): Define.
(R_ARM_FUNCDESC_VALUE): Define.
* ldso/include/dl-string.h (SEND_STDERR, SEND_ADDRESS_STDERR)
(SEND_NUMBER_STDERR): Define empty for __FDPIC__.
* ldso/ldso/arm/dl-inlines.h: New file.
* ldso/ldso/arm/dl-startup.h (PERFORM_BOOTSTRAP_RELOC): Fix type
of load_addr. Fix handling of R_ARM_RELATIVE, add support for
R_ARM_FUNCDESC_VALUE.
(DL_START, START): Define for __FDPIC__.
(raise): Define.
* ldso/ldso/arm/dl-sysdep.h (ARCH_NEEDS_BOOTSTRAP_RELOCS): Define.
(DL_CHECK_LIB_TYPE): Define.
(elf_machine_type_class): Take into account FDPIC related
relocations.
(elf_machine_load_address): Support __FDPIC__.
(elf_machine_relative): Likewise.
* ldso/ldso/arm/elfinterp.c (_dl_linux_resolver): Dummy support
for __FDPIC__, implemented in a later patch.
(_dl_do_reloc): Fix reloc_adr computation for __FDPIC__, fix
handling of local symbols. Fix handling of R_ARM_RELATIVE, add
support for R_ARM_FUNCDESC_VALUE, R_ARM_FUNCDESC.
* ldso/ldso/arm/resolve.S: Make _dl_linux_resolve hidden.
* ldso/ldso/fdpic/dl-inlines.h (htab_delete): Declare.
* libc/sysdeps/linux/arm/bits/elf-fdpic.h: New file, similar to bfin's.
* libc/sysdeps/linux/arm/crtreloc.c: Likewise.
* libc/sysdeps/linux/arm/find_exidx.c (__dl_addr_in_loadaddr) Define.
(find_exidx_callback): Support __FDPIC__.

Similar to musl libc a single libc has many benefits and solves
some open issues with uClibc-ng.
- no pthread_mutex_* weak symbols exported anymore
- applications no longer failing to link when either
-lrt or -lpthread are missing for dynamic and static linking mode
- smaller C library
- slightly better runtime performance

The FR-V port is really broken, and I have no emulator
or hardware for this platform. I tried to get some hardware
from RedHat, who made the FR-V port initially. Unfortunately
Fujitsi didn't agreed to sent me some of their unused spare
hardware lying @RedHat. As I invested some time to get stuff compiled,
I decided to add the code and may be anytime later I can gain
access to some emulator or hardware.
GDB simulator for FR-V doesn't support booting Linux AFAIK.

The fdpic support has been broken since the prelink support was added,
because it didn't take into account DL_LOADADDR_TYPE could be a different
type of ElfW(Addr).

There should (hopefully) be no functional changes here.

Much of the logic in the bfin/frv subdirs is FDPIC specific and not arch
specific. So start a new fdpic/ subdir to keep common things.
