Unrolled build for rust-lang#131169

Rollup merge of rust-lang#131169 - madsmtm:target-info-nto-vendor, r=wesleywiser

Fix `target_vendor` in QNX Neutrino targets

The `x86_64-pc-nto-qnx710` and `i586-pc-nto-qnx700` targets have `pc` in their target triple names, but the vendor was set to the default `"unknown"`.

CC target maintainers `@flba-eb,` `@gh-tr,` `@jonathanpallant` and `@japaric`
