chore: fix some comments

remove redundant word in comment

[sunfishcode]

Those words aren't redundant; "linked in" is a phrasal verb meaning that a library is included is the final output, and "in lto builds" is a prepositional phrase describing a build configuration. That said, I'm open to ideas for how to improve the wording to clarify this comment.

Thank you for the clarification on the phrasal verb usage. The revised comment now preserves "linked in" as a verb phrase while making these improvements:

1. Technical precision: Differentiates between .weak (handling symbol visibility) and .ifndef (preprocessor collision avoidance)

2. Build context clarity: Uses parallel structure for "non-LTO builds" vs "LTO builds"
