More record.c build failures

["Pierre Muller" <muller@ics.u-strasbg.fr>]

record.c is bound to give problems
on all targets that do not compile gcore.c 
source.

  gcore.o  is a optional object that
is only added to the list of compiled
object in the config directory.

  Thus it is not possible to 
use this without some configure test...

This is the outcome of
Cygwin compilation with beta cygwin 1.7:

gcc -g -O2   -Wl,--stack,8388608   \
		-o gdb.exe gdb.o libgdb.a \
		   ../readline/libreadline.a ../opcodes/libopcodes.a
../bfd/libbfd.a -lintl ../libiberty/libiberty.a
../libdecnumber/libdecnumber.a    -ltermcap -lz -lm   -liconv -lexpat
../libiberty/libiberty.a -luser32 -limagehlp gnulib/libgnu.a 
libgdb.a(record.o): In function `cmd_record_save':
/home/Famille/gdbcvs/build-norm/gdb/../../src/gdb/record.c:2223: undefined
reference to `_create_gcore_bfd'
/home/Famille/gdbcvs/build-norm/gdb/../../src/gdb/record.c:2280: undefined
reference to `_write_gcore_file'
collect2: ld returned 1 exit status
make[1]: *** [gdb.exe] Error 1

Can someone fix this, please?
