Fix pcm_read_seek () when the position it calculates is greater than 2 GB.

pcm_read_seek() puts the return value of url_fseek() in an int and then
compares < 0 to see if an error occurred; if the position is greater
than 2 GB, the 32-bit signed int result will be < 0.

Change the type of ret to int64_t to avoid the wraparound.

Re-add check for compilation failure with ebx clobber, and only set
ebx_available if both "b" constraint and exb clobber code compile.
This is to fix compilation with Mac OSX 10.5.8's gcc 4.0.1 in 64
bit mode (-m64) which only fails for ebx/rbx clobbers but not
"b" constraints - this is probably a compiler bug.
