(DBG_S_C_REAL8_G, DBG_S_C_COMPLX8_G): G_float versions of
REAL8 and COMPLX8; not used yet, because gcc outputs the same
.stabs for `double' regardless of whether `-mg' is used.

for gcc2's predefined types "complex float", "complex double",
and "complex long double" (identical to complex double).

argument, not bfd *. Clean up. Change all callers.
(ldfile_open_file): If doing a dynamic link, call
ldemul_open_dynamic_archive rather than assuming the extension of
a dynamic object is ".so".

New function.
(ld_${EMULATION_NAME}_emulation): Initialize open_dynamic_archive
field.

handle it.
* ldmain.c (main): Initialize command_line.interpreter to NULL.
* emultempl/elf32.em (gld${EMULATION_NAME}_before_allocation): Get
the ELF backend to return the .interp section. If
command_line.interpreter is not NULL, set the contents of .interp
to it.
* ld.texinfo: Mention -dynamic-linker.
argument, and set it to the .interp section.
* bfd-in.h (bfd_elf32_size_dynamic_sections): Update prototype.
(bfd_elf64_size_dynamic_sections): Likewise.

(EXPECT, RUNTEST, CC): Fix relative pathname.
(site.exp): Don't insert host_os, etc.
* gdb.base/signals.c (main): Don't call signal unless SIGALRM
and/or SIGUSR1 defined.
