nvptx: In 'STARTFILE_SPEC', fix 'crt0.o' for '-mmainkernel'
A recent nvptx-tools change: commit 886a95faf66bf66a82fc0fe7d2a9fd9e9fec2820
"ld: Don't search for input files in '-L'directories" (of
<https://github.com/MentorEmbedded/nvptx-tools/pull/38>
"Match standard 'ld' "search" behavior") in GCC/nvptx target testing
generally causes linking to fail with:
error opening crt0.o
collect2: error: ld returned 1 exit status
compiler exited with status 1
Indeed per GCC '-v' output, there is an undecorated 'crt0.o' on the linker
('collect2') command line:
[...]/build-gcc/./gcc/collect2 -o [...] crt0.o [...]
This is due to:
gcc/config/nvptx/nvptx.h:#define STARTFILE_SPEC "%{mmainkernel:crt0.o}"
..., and the fix, as used by numerous other GCC targets, is to instead use
'crt0.o%s'; for '%s' means, per 'gcc/gcc.cc', "The Specs Language":
%s current argument is the name of a library or startup file of some sort.
Search for that file in a standard list of directories
and substitute the full name found.
With that, we get the expected path to 'crt0.o'.

* config/nvptx/nvptx.h (STARTFILE_SPEC): Fix 'crt0.o' for
'-mmainkernel'.
