The implementation of strtorQ is imported from FreeBSD's gdtoa library (By David
M. Gay) with some adaptations to fit with newlib.
`strtorQ.c` enables `strtold` to perform correct parsing on targets where long
double uses the IEEE754 binary128 format (113-bit mantissa), such as AArch64.
Without this patch, strtold would wrongly fallback to `strtorx` which will
parse into a 80-bit long double and give invalid result.
* libc/stdlib/strtorQ.c: New file, adapted from FreeBSD gdtoa.
* libc/stdlib/strtold.c (_strtold_impl): New helper selecting strtorx
for 80-bit and strtorQ for 128-bit long double.
(_strtold_r, strtold_l, strtold): Use _strtold_impl.
* libc/stdlib/mprec.h (_strtorQ_l): Declare.
* libc/stdlib/Makefile.inc (libc_a_SOURCES): Add strtorQ.c.
* newlib/Makefile.in: Regenerate with automake
